TOI-6054.01
TOI-6054.01 is a super-Earth orbiting TOI-6054 in the constellation Camelopardalis. It lies about 259 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-6054.01?
TOI-6054.01 has a radius of 2.64 times that of Earth. Its mass is 12.5 times that of Earth, giving it a density of 3.70 g/cm³ — between that of rocky and gaseous planets.
Is TOI-6054.01 in the Habitable Zone?
TOI-6054.01 orbits inside the inner edge of the habitable zone of TOI-6054. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-6054: 1.347–3.153 AU (conservative: 1.706–2.990 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-6054.01
The equilibrium temperature of TOI-6054.01 is about 1,360 K (1,087 °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. It receives 570 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-6054.01 — one full orbit around TOI-6054 — lasts 7.50 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.076 AU — closer to its star than Mercury is to the Sun. Its orbit is mildly elliptical (eccentricity 0.16).
How Was TOI-6054.01 Discovered?
TOI-6054.01 was discovered in 2024 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-6054.01?
TOI-6054.01 is 259.0 light-years (79.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1767. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 4,558,400 years to make the journey.

Frequently Asked Questions About TOI-6054.01
Is TOI-6054.01 habitable?
No — TOI-6054.01 orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-6054.01?
TOI-6054.01 is about 259 light-years from Earth in the constellation Camelopardalis. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 4,558,400 years to get there.
How big is TOI-6054.01 compared to Earth?
TOI-6054.01 has 2.64 times the radius of Earth and about 12.5 times its mass.
How long is a year on TOI-6054.01?
One orbit around TOI-6054 takes 7.5 Earth days — short enough that 49 of its years would fit into one Earth year.
