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 5.20 times that of Earth. Its mass is 22.4 times that of Earth, giving it a density of 0.87 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TOI-1710 b in the Habitable Zone?
TOI-1710 b orbits inside the inner edge of the habitable zone of TOI-1710. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-1710: 0.701–1.657 AU (conservative: 0.889–1.571 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-1710 b
The equilibrium temperature of TOI-1710 b is about 603 K (330 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
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 0.166 AU — closer to its star than Mercury is to the Sun.
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 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About TOI-1710 b
Is TOI-1710 b habitable?
No — TOI-1710 b orbits too close to its star and is too hot for liquid water to exist on its surface.
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 5.20 times the radius of Earth and about 22.4 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.
