TRAPPIST-1e
Planet hop from TRAPPIST-1e
Seven Earth-sized worlds orbit tightly around a dim red-dwarf star called TRAPPIST-1, about 40 light-years away. The entire system would fit inside the orbit of Mercury in our own solar system.
However, because the star is so cool and small -- hardly bigger than Jupiter -- some of the seven might be temperate.
This planet, TRAPPIST-1e, is the fourth planet from the star, and sits right in the middle of the habitable zone, the distance from a star where liquid water could exist on a planet’s surface.

The TRAPPIST-1 star is visible from Earth in the Aquarius constellation, so the opposite must be true from TRAPPIST-1e: Our Sun appears in the opposite of Aquarius, which is Leo.
Our Sun, seen here, would appear as a yellow star in its night sky.
We are the Leo Sun from TRAPPIST-1! Our Sun is part of the Leo constellation, seen here.
If you were to stand on any one of these worlds, you would be able to see other planets in the system. If the planets have continents and oceans you would be able to see them!
The artists worked with scientists to calculate when the planets would align and this is how they would appear, hanging like large moons in the sky. That gave rise to the idea that in the future, people might travel to see such celestial events, much like people today travel to see eclipses.
