“If you hate it here, why don’t you just leave?” That phrase annoys me, but what if you despise every coordinate on Earth? After all, are we here for the universe or is the universe here for us? Well, here’s the list of planets that you should build your dream civilization on (or just keep it all for yourself).
Kepler 452B
The Pros:
Described as the Earthiest planet besides Earth itself, Kepler 452B boasts a mass more than thrice that of Earth—exciting if you find today’s real estate prices a bit much! The host star, Kepler 452, is comparable to earth, only about 11 percent larger and about the same temperature. Furthermore, the planet’s temperature is theorized to be like Earth’s, if not slightly warmer. Finally, the time Kepler 452B takes to orbit is 384.8 days, not too much longer than the Earth around the Sun.
The Cons:
Kepler 452’s surface likely contains a higher number of volcanoes than Earth, due to its higher mass; maybe a home on the coast could work, as water may theoretically be present? Secondly, although oxygen may be present in the atmosphere, it will also be cloudy most of the time.
Trappist 1e
The Pros:
Compared to Kepler 452B, it will be easier to get to (only ~40 light years instead of 1,400), and the atmosphere may be less dense. In addition, the host star, Trappist, although quite small compared to the sun, has a life span about two-thousand times greater, so if you manage to live a few trillion years, you won’t have to worry about Trappist being exhausted. Trappist 1e is about ninety percent the size of earth and has ninety three percent of the surface gravity. In terms of temperature, it’s theorized to be somewhere between Earth and Mars allowing for the presence of liquid water; I guess just bring a space heater.
Cons:
Firstly, since Trappist is small, the time to complete an orbit is only ~six Earth days, meaning if you like the seasons on Earth, this planet may not be for you. Also, the Trappist system is in the Aquarius constellation, thus, if you’re not an Aquarius, you won’t fit in, sorry to discriminate. ‘
Teegarden B
The Pros:
Firstly, even compared to Trappist 1e, it is even easier to get to, since Teegarden B sits only 12.5 light years away. Teegarden B is only slightly heavier than Earth and the estimate of its radius is yields one nearly identical to Earth’s. Compared to Teegarden C, B has a higher likelihood of featuring human-friendly temperatures, estimated at a 60 percent confidence. Because of this temperature, water may form on the surface—vital for any life-sustaining planet as we know it.
The Cons:
Firstly, the Teegarden Star is only a tenth of the size of the sun and is dim. Secondly, the time Teegarden B takes to orbit Teegarden is about five days. Finally, since Teegarden B sits so close to its star, it is tidally locked, meaning one face of the planet faces the Teegarden all the time; one side of the planet is nice and warm, the other is perpetually cold and dark.
