help Kepler-90h FAQ

How long is one year on Kepler-90h?

Kepler-90h takes about 332 Earth days to orbit its star. Despite that Earth-like orbital period, it is a large gas giant and is much larger than Earth.

How large is Kepler-90h?

It is roughly Jupiter-sized, at about 11 Earth radii. The planet is therefore a gas giant rather than a rocky world suitable for an Earth-like surface.

Why is Kepler-90h historically important?

Kepler-90 became the first known exoplanet system with eight confirmed planets, matching the number in our Solar System. NASA and Google announced the identification of the eighth planet, Kepler-90i, in 2017.

Where is the Kepler-90 system?

Kepler-90 is roughly 2,500 light-years from Earth in the constellation Draco. The system was studied using data from NASA's Kepler space telescope and later machine-learning analysis.
