The OGLE-2018-BLG-0677L Exoplanetary System
OGLE-2018-BLG-0677L is a star with 0.12 times the mass of the Sun, and 0.14199999999999985 times its radius. It is located 24722.62 light years away from the solar system.
OGLE-2018-BLG-0677L is known to have 1 exoplanets in orbit around it.
OGLE-2018-BLG-0677L b was discovered by the OGLE observatory using the microlensing method. Its discovery was announced in 2020-05. Its semi-major axis is 0.63 astronomical units, as compared to Earth's which is 1 astronomical unit.
The mass of OGLE-2018-BLG-0677L b is 3.96 times the mass of Earth. At 3.96 Earth masses, OGLE-2018-BLG-0677L b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. No Super Earths are known to exist in our solar system, but if it exists, the so-called Planet Nine could very well be a super Earth, as it is hypothesized to have a mass between five and ten Earth masses.
