Kepler-1423 and Its Earth-like Planet
Kepler-1423 is a star with one known planet in its system. The host star is estimated to be 4.68 billion years old, with a mass of 0.79 solar masses and a radius of 0.75 solar radii. Its reported temperature is 4940 K.
The star's reported mass estimate is smaller than the Sun's, and its reported radius estimate is also smaller than the Sun's. Its reported temperature is cooler than the Sun's.
The sole cataloged planet, Kepler-1423 b, is classified as Earth-like. It was discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Repeated dips help establish orbital periods.
Kepler-1423 b has an orbital period of 24 days and a radius of 1.06 Earth radii. Its size classification compares radius with Earth's: an Earth-like planet stays within 1.5 times Earth's radius.
