ITG 15 b
ITG 15 b is a exoplanet orbiting ITG 15 A in the constellation Taurus. It lies about 445 light-years from Earth and was discovered in 2024 using the imaging method.
Is ITG 15 b in the Habitable Zone?
The position of ITG 15 b relative to the habitable zone of ITG 15 A cannot be precisely determined from the available orbital data.
Temperature on ITG 15 b
The equilibrium temperature of ITG 15 b is about 2,601 K (2,328 °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
ITG 15 b orbits at an average distance of 435.000 AU.
How Was ITG 15 b Discovered?
ITG 15 b was discovered in 2024 using the imaging method, with observations from European Space Agency (ESA) Gaia Satellite.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is ITG 15 b?
ITG 15 b is 444.8 light-years (136.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1582. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 7,828,480 years to make the journey.
The Host Star: ITG 15 A
ITG 15 b belongs to a system of 2 stars; it orbits ITG 15 A.
