Trappist-1d Landscape

 

Digital Art, 2017

These four images show the landscape of a planet that was recently discovered in the solar system Trappist-1. It is 39 light-years away from Earth in the constellation of Aquarius. It has an M-type ultra-cool dwarf star known as Trappist-1a. There are a total of 7 planets in this solar system. 3 of which are in the habitable zone (Trappist-1 d, e, and f). The planet I choose was Trappist-1d because after doing some research, this planet seemed to interest me the most. This planet’s distance from the star is 0.021 AU (The third planet from the Sun). It has a similar atmosphere as Mars with an average temperature of 288 K. The orbital period 6.10 days which is way faster than Earth’s 365 days period. Planet mass is 0.41 ± 0.27 M-, density is 4.91 ± 3.31 g cm^-3, surface gravity is 0.69 g (Standard Gravity, 69% of Earth value) and radius is 0.772 ± 0.030 R- Intermediate in size between Mars (with a radius about half that of Earth) and Earth. This planet has no moons, but all 6 of the other planets are visible in the sky.
