Is TCP J05074264+2447555 b in the Habitable Zone?
The position of TCP J05074264+2447555 b relative to the habitable zone of TCP J05074264+2447555 cannot be precisely determined from the available orbital data.
Orbit and Year Length
TCP J05074264+2447555 b orbits at an average distance of 0.940 AU — comparable to the inner Solar System.
How Was TCP J05074264+2447555 b Discovered?
TCP J05074264+2447555 b was discovered in 2018 using the microlensing method, with observations from Multiple Observatories.
Gravitational microlensing detects a planet when its host star passes in front of a more distant background star, and the planet's gravity adds a brief, telltale spike to the magnified starlight. It can find planets thousands of light-years away.
How Far Away Is TCP J05074264+2447555 b?
TCP J05074264+2447555 b is 1,647.1 light-years (505.0 parsecs) from Earth. Light arriving here tonight left the planet about 1,647 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 28,988,960 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. TCP J05074264+2447555 b scores 0.46, ranking #314 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
