Kepler-1284 and Its Earth-Like Planet
Kepler-1284 is a star 2880 light-years away with one known planet. The star is estimated to be 4.47 billion years old and has a mass of 0.84 solar masses, a radius of 0.79 solar radii, and a temperature of 5120 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler than the Sun's.
The planet Kepler-1284 b was discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Kepler-1284 b is classified as Earth-like, meaning its radius stays within 1.5 times Earth's radius. Its radius is 1.21 Earth radii, larger than Earth's, and it completes an orbit in 0.664 days.
