Kepler-186f

The First Earth Sized Planet

Planetary Description

Kepler-186f is the first near-Earth-size planet orbiting a star in the "habitable zone". The range of distance from a star where liquid water might pool on the surface of an orbiting planet. Kepler-186f resides in the Kepler-186 system about 500 light-years from Earth in the constellation Cygnus. The system is also home to four inner planets, seen lined up in orbit around a host star that is half the size and mass of the sun.

The star would appear 30% larger in the sky if you were standing on it due to the proximity of the planet on the habitable zone to its star

If your spaceship can travel at 0.1c, how long would it take you to travel to your planet? How old will you be when you arrive?

It will take 5,000 years to get to my planet and when I arrive to it, I will be 5,014 years old.

3 interesting facts about Kepler-186f

• its on the outer edge of the habitable zone, so it's possible that the plants' water could freeze.

• its one of the five planets found in the extrasolar system located about 500 light-years from earth.

• if it were to circle the sun, it would travel within the orbit of the planet Mercury, a planet that is not considered habitable.

3 problems that I would experience if I tried to live on Kepler-186f

• the surface temperatures would generally be above freezing and below boiling

• there could be liquid oceans

• liquid water is any astrobiologist's faborite tipoff that life might be present.

How could I overcome these problems to make my planet suitable for human life?

I would get certain suits in order for me to get in my planet without worrying about the temps tired or the liquid oceans making it suitable for me to live on my planet.
