Kepler-1498 and Its Earth-Like Planet

Kepler-1498 is a star with one known planet. The host star is 4.17 billion years old, has a mass of 0.86 solar masses, and a radius of 0.81 solar radii, making it smaller than the Sun in both mass and radius. Its temperature is 5260 K, which is cooler than the Sun's. The reported mass, radius, and temperature differences from the Sun are estimates rather than exact values.

The single planet orbiting this star is Kepler-1498 b, an Earth-like world discovered in 2016 by the transit method, in which a planet crosses in front of its star and causes a small dip in brightness. Kepler-1498 b completes an orbit every 48.1 days. Its radius is 1.33 Earth radii, which is larger than Earth's. As an Earth-like planet, it falls within 1.5 times Earth's radius, a size class based on radius rather than composition.
