EPIC 206024342 d
EPIC 206024342 d is a mini-Neptune orbiting EPIC 206024342 in the constellation Aquarius. It lies about 1,206 light-years from Earth and was discovered in 2021 using the transit method.
How Big Is EPIC 206024342 d?
EPIC 206024342 d has a radius of 2.60 times that of Earth.
Is EPIC 206024342 d in the Habitable Zone?
The position of EPIC 206024342 d relative to the habitable zone of EPIC 206024342 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on EPIC 206024342 d — one full orbit around EPIC 206024342 — lasts 14.6 Earth days, shorter than Mercury's 88-day year.
How Was EPIC 206024342 d Discovered?
EPIC 206024342 d was discovered in 2021 using the transit method, with observations from K2.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is EPIC 206024342 d?
EPIC 206024342 d is 1,206.4 light-years (369.9 parsecs) from Earth. Light arriving here tonight left the planet about 1,206 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 21,232,640 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. EPIC 206024342 d scores 0.25, ranking #3,087 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
