TOI-907.01
TOI-907.01 is a hot Jupiter orbiting TOI-907 in the constellation Ara. It lies about 1,019 light-years from Earth and was discovered in 2024 using the transit method.
How Big Is TOI-907.01?
TOI-907.01 has a radius of 9.62 times that of Earth, or 0.86 times the radius of Jupiter.
Is TOI-907.01 in the Habitable Zone?
TOI-907.01 orbits inside the inner edge of the habitable zone of TOI-907. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TOI-907: 1.768–4.118 AU (conservative: 2.239–3.905 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TOI-907.01
The equilibrium temperature of TOI-907.01 is about 1,847 K (1,573 °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 1,730 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on TOI-907.01 — one full orbit around TOI-907 — lasts 4.58 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.055 AU — closer to its star than Mercury is to the Sun.
How Was TOI-907.01 Discovered?
TOI-907.01 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-907.01?
TOI-907.01 is 1,019.3 light-years (312.5 parsecs) from Earth. Light arriving here tonight left the planet around the year 1007. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 17,939,680 years to make the journey.

Frequently Asked Questions About TOI-907.01
Is TOI-907.01 habitable?
No — TOI-907.01 orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is TOI-907.01?
TOI-907.01 is about 1,019 light-years from Earth in the constellation Ara. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 17,939,680 years to get there.
How big is TOI-907.01 compared to Earth?
TOI-907.01 has 9.62 times the radius of Earth.
How long is a year on TOI-907.01?
One orbit around TOI-907 takes 4.6 Earth days — short enough that 80 of its years would fit into one Earth year.
