The iot Dra Exoplanetary System
iot Dra is a star with 1.05 times the mass of the Sun, and 1.066 times its radius. It is located 103.29 light years away from the solar system.
iot Dra is known to have 1 exoplanets in orbit around it.
iot Dra b
iot Dra b was discovered by the Lick Observatory observatory using the radial velocity method. Its discovery was announced in 2002-09. Its semi-major axis is 1.27 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 511.10 Earth days to complete an orbit around its host star, iot Dra.
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 0.7124, which means that when iot Dra b is at is at its closest point to its host star, 0.37 astronomical units separates the two, and when it is at its farthest point, this number is 2.18. In the case of Earth, these numbers are 0.9832899 and 1.0167103 respectively.
The mass of iot Dra b is 2803.09 times the mass of Earth. At more than 50 Earth masses, iot Dra 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.
