Is TYC 8998-760-1 b in the Habitable Zone?
The position of TYC 8998-760-1 b relative to the habitable zone of TYC 8998-760-1 cannot be precisely determined from the available orbital data.
Orbit and Year Length
TYC 8998-760-1 b orbits at an average distance of 146.000 AU. Its orbit is highly elliptical (eccentricity 0.44), swinging dramatically closer to and farther from its star.
How Was TYC 8998-760-1 b Discovered?
TYC 8998-760-1 b was discovered in 2020 using the imaging method, with observations from Paranal Observatory.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is TYC 8998-760-1 b?
TYC 8998-760-1 b is 308.6 light-years (94.6 parsecs) from Earth. Light arriving here tonight left the planet around the year 1718. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 5,431,360 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. TYC 8998-760-1 b scores 0.07, ranking #4,880 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
