| Planet type | Planet |
| The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to Kepler-450 A, which reoccurs over the so-called synodic period approximately every 64 days.
As seen relative to the fixed stars, it rotates on its axis exactly five times for every five revolutions it makes around Kepler-450 A.
It has the densest atmosphere of the planets, consisting partly of helium. The krypton has probably photodissociated, and the free helium has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field. |
