TOI-1710 b
TOI-1710 b is a Neptune-like planet orbiting TOI-1710 in the constellation Camelopardalis. It lies about 265 light-years from Earth and was discovered in 2022 using the transit method.
How Big Is TOI-1710 b?
TOI-1710 b has a radius of 5.26 times that of Earth. Its mass is 13.2 times that of Earth, giving it a density of 0.50 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-1710 b in the Habitable Zone?
The position of TOI-1710 b relative to the habitable zone of TOI-1710 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on TOI-1710 b — one full orbit around TOI-1710 — lasts 24.3 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.163 AU — closer to its star than Mercury is to the Sun. Its orbit is nearly circular (eccentricity 0.040).
How Was TOI-1710 b Discovered?
TOI-1710 b was discovered in 2022 using the transit method, with observations from Transiting Exoplanet Survey Satellite (TESS).
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 TOI-1710 b?
TOI-1710 b is 264.9 light-years (81.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1762. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,662,240 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. TOI-1710 b scores 0.17, ranking #4,065 of 5,566 planets with a known ESI. For reference, Mars scores about 0.70.
The Host Star: TOI-1710

Frequently Asked Questions About TOI-1710 b
Is TOI-1710 b habitable?
TOI-1710 b is not known to orbit within the habitable zone of TOI-1710, and as a Neptune-like planet it is an unlikely candidate for life as we know it.
How far away is TOI-1710 b?
TOI-1710 b is about 265 light-years from Earth in the constellation Camelopardalis. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,662,240 years to get there.
How big is TOI-1710 b compared to Earth?
TOI-1710 b has 5.26 times the radius of Earth and about 13.2 times its mass.
How long is a year on TOI-1710 b?
One orbit around TOI-1710 takes 24.3 Earth days — short enough that 15 of its years would fit into one Earth year.
