The RR Cae Exoplanetary System
RR Cae is a star with 0.44 times the mass of the Sun, and 0.5399999999999998 times its radius. It is located 69.15 light years away from the solar system.
RR Cae is known to have 1 exoplanets in orbit around it.
RR Cae b
RR Cae b was discovered by the Leoncito Astronomical Complex observatory using the eclipse timing variations method. Its discovery was announced in 2012-05. Its semi-major axis is 5.30 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 4343.50 Earth days to complete an orbit around its host star, RR Cae.
Its eccentricity, the extent to which the shape of the exoplanet's orbit departs from a perfect circle (Earth's is 0.0167, which is why the shape of Earth's orbit is circular rather than oval in appearance), is 0, which means that when RR Cae b is at is at its closest point to its host star, 5.30 astronomical units separates the two, and when it is at its farthest point, this number is 5.30. In the case of Earth, these numbers are 0.9832899 and 1.0167103 respectively.
The mass of RR Cae b is 1334.80 times the mass of Earth. At more than 50 Earth masses, RR Cae b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
