#10: TrES-2b — The Dracula Planet

Image used with permission by copyright holder

Our first stop is the pitch black planet TrES-2b. This gas giant’s atmosphere is less reflective than coal, but as hot as the hottest Earth-born lava. These two odd properties give the planet an eerie red glow, so if you’re a fan of horror stories and Lovecraftian lore, then this might be the perfect stop for you.

Pros: It’s the perfect setting for any of your spooky Halloween parties or vampire cult get-togethers.
Cons: While the red glow may deliver the spooky vibe you’re after, it will also reduce your party to ash as soon as you arrive.

#9: Kepler-36c/b — That’s no moon!

Second on this journey are the two planets Kepler-36 C and B. These celestial bodies pass by each other at a distance that’s roughly four times the distance between Earth and the Moon — thereby providing a remarkable view of either planet from the other’s surface.

Pros: A beautiful view of either planet as they pass each other like ships in the night.
Cons: This view will likely be your last, as neither planet is anywhere near hospitable.

#8: OGLE-2005-BLG-390 — Love the snow? This one is nicknamed ‘Hoth’

Are you a fan of the snow, always looking for the freshest slope? Then OGLE-2005-BLG-390, nicknamed ‘Hoth’, is the exoplanet for you! At negative 220 degrees Celsius, this planet is in a perpetual deep freeze — presumably creating endless slopes for you to carve up.

Pros: It’s an entire planet of slopes for you and your crew to cruise down on your space skis.
Cons: On the other hand, the lack of atmosphere an precipitation means it’s likely solid ice — just like you’d be shortly after arrival.

#7: PSR B1257+12 system — A light show to die for

The Aurora Borealis is one of Earth’s greatest sights, but it’s a firefly in the night compared to the light shows caused by PSR B1257+12. This pulsar is the remnants of a star gone supernova, which constantly whips the planets around it with tendrils of radiation — causing planet-wide lights in the sky.

Pros: This place boasts the most impressive auroras you’ll ever see.
Cons: Your DNA would immediately be scrambled and fried by the astronomical levels of radiation.

#6: 55 Cancri e — An intergalactic prospector’s dream

Are you a more adventurous type, lusting for the days of old when you could make your fortune on the frontier? Then get your gear together and head to 55 Cancri e, a planet whose composition is largely carbon. This makeup results in the planet being almost entirely made of precious metals, both inside and out.

Pros: The potential to become a space mining tycoon with zillions of blemflarcks (or whatever currency we use in the future)
Cons: All those precious metals are hot as hell and currently in liquid form, so good luck with that!

#5: Kepler-16b — Where your shadow will never be lonely

Kepler-16b itself is not especially interesting, but what it’s orbiting definitely is. This exoplanet orbits two stars. That’s right folks, not one, but TWO stars. Look forward to never before seen sunsets and sunrises, and a pal for your shadow.

Pros: A one in a million sky. Woo any potential partner with a romantic picnic beneath a double sunset.
Cons: Unfortunately the planet itself is VERY cold, even with two stars. Let’s just say you’re going to need a LOT of picnic blankets.

#4: Wasp 12 b — A crumbling planet being eaten by its sun

For those of you looking for a bit more of an extreme sightseeing experience, Wasp 12 b is everything you could ask for. This planet is slowly being “eaten” by its star, and the side facing the star is crumbling and forming a ring of debris along its orbit. If you’re into those high budget scenes in apocalypse movies, you’re going to LOVE this.

Pros: Probably the most metal thing you will ever see in your life.
Cons: This should be obvious, but if the planet is dissolving, you’re not going to do too well yourself.

#3: Kepler-452b — Earth’s bigger, older cousin

Image used with permission by copyright holder

So death defying sights and experiences aren’t your thing, and you’re looking for a new place or a summer home? Welcome to Kepler-452b: Earth’s bigger, older cousin. With a 385 day orbit, a rocky exterior, and 60% more mass than Earth; it’s a new frontier that’s both vast and vaguely familiar.

Pros: Finding your own special place won’t be hard with all this space, and the years are just about the same length as Earth’s.
Cons: Aside from that, the place is pretty boring. As far as we know, it’s the only planet orbiting this star, and has no moons. It’s also 1400 light years away, so say goodbye to your fam here on Earth.

#2: Proxima B — Only a hop, skip, and four light years away

Image used with permission by copyright holder

Unlike our last home away from home, Proxima B orbits Proxima Centauri: the closest star to our Sun, which sits just a few short light years away. With a rocky red exterior like our neighbor Mars and a member of the infamous Alpha Centauri system, this could be your summer getaway to your own red skied paradise.

Pros: It’s only four light years away, making it the best candidate for potential colonization. There’s also a red landscape that gives it that homey Mars feel, and multiple nearby stars in the sky,.
Cons: Unfortunately, signs for this planet being habitable are slim. Its star is old and radioactive, and its orbit takes only 11 days. Not to mention that it is likely tidally locked like our moon. Bummer.

#1: Trappist-1 System — A fistfull of Earths

Welcome to the Trappist-1 system, seven tightly bundled planets orbiting an ultra-cool dwarf star, and are all suspected to harbor rocky surfaces. Due to the nature of this system’s sun, it’s possible that the majority of these planets harbor liquid water as well — making this system a treasure trove of habitable planets.

If that isn’t enough to wet your whistle, these planets are also VERY close to each other. Close enough that while standing on any of them, other planets would be near enough that you could see clouds and large geological features with your naked eyes.

As most of these planets are potentially habitable, you’d get your pick of the litter when it comes time to settle down and build a colony. For these reasons, the Trappist-1 system comes thundering into first place on our list of Top Ten Exoplanets.

Pros: Multiple planets to settle, liquid water, non gaseous planets, and close interplanetary proximity. It also has a really neat sky, and isn’t near anything that’s going to kill you — like a black hole or a radiation-spewing pulsar.

Cons: Two big things: this system is 39 light years away, and it’s suspected that all of these planets are tidally locked due to their proximity to their star — meaning the weather on each planet would be wildly unlike Earth’s.

James Webb photographs two potential exoplanets orbiting white dwarfs

Even though scientists have now discovered more than 5,000 exoplanets, or planets outside our solar system, it's a rare thing that any telescope can take an image of one of these planets. That's because they are so small and dim compared to the stars that they orbit around that it's easier to detect their presence based on their effects on the star rather than them being detected directly.

However, thanks to its exceptional sensitivity, the James Webb Space Telescope was recently able to image two potential exoplanets orbiting around small, cold cores of dead stars called white dwarfs directly.

Astronomers discover a super-Earth located in the habitable zone
This illustration shows one way that planet TOI-715 b, a super-Earth in the habitable zone around its star, might appear to a nearby observer.

Astronomers have discovered a type of exoplanet called a "super-Earth" located in the habitable zone of its small star, and it's right in our cosmic backyard, just 137 light-years away. The planet, named TOI-715 b, is intriguing to astronomers who are increasingly interested in the possibility of habitable planets orbiting stars quite different from our sun.

Although it might seem to make sense to look for potentially habitable planets when looking for Earth-like planets orbiting sun-like stars, those aren't the only targets that astronomers are interested in. One issue is that most discovered exoplanets are much larger than Earth, partly because it is so hard to detect smaller planets. Another issue is that the most common star in our galaxy by far is not a yellow dwarf star like our sun, but a smaller, dimmer, redder type called a red dwarf. When researchers discover rocky planets orbiting around red dwarfs, a few of which have been identified to date, that increases the pool of potentially habitable worlds that could be out there.

Small exoplanet could be hot and steamy according to Hubble
This is an artist’s conception of the exoplanet GJ 9827d, the smallest exoplanet where water vapour has been detected in its atmosphere. The planet could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. It is a rocky world, only about twice Earth’s diameter. It orbits the red dwarf star GJ 9827. Two inner planets in the system are on the left. The background stars are plotted as they would be seen to the unaided eye looking back toward our Sun, which itself is too faint to be seen. The blue star at upper right is Regulus, the yellow star at bottom centre is Denebola, and the blue star at bottom right is Spica. The constellation Leo is on the left, and Virgo is on the right. Both constellations are distorted from our Earth-bound view from 97 light-years away.

One of the big topics in exoplanet research right now is not just finding exoplanets but also looking at their atmospheres. Tools like the James Webb Space Telescope are designed to allow researchers to look at the light coming from distant stars and see how it is filtered as it passes by exoplanets, allowing them to learn about the composition of their atmospheres. But scientists are also using older telescopes like the Hubble Space Telescope for similar research -- and Hubble recently identified water vapor in an exoplanet atmosphere.

“This would be the first time that we can directly show through an atmospheric detection that these planets with water-rich atmospheres can actually exist around other stars,” said researcher Björn Benneke of the Université de Montréal in a statement. “This is an important step toward determining the prevalence and diversity of atmospheres on rocky planets."
