TIC 183374187 b
TIC 183374187 b is a hot Jupiter orbiting TIC 183374187 in the constellation Phoenix. It lies about 3,942 light-years from Earth and was discovered in 2026 using the transit method.
How Big Is TIC 183374187 b?
TIC 183374187 b has a radius of 14.03 times that of Earth, or 1.25 times the radius of Jupiter. Its mass is 178 times that of Earth, giving it a density of 0.35 g/cm³ — closer to gas planets like Jupiter (1.33 g/cm³).
Is TIC 183374187 b in the Habitable Zone?
The position of TIC 183374187 b relative to the habitable zone of TIC 183374187 cannot be precisely determined from the available orbital data.
Habitable zone of TIC 183374187: 1.006–2.370 AU (conservative: 1.274–2.247 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on TIC 183374187 b
The equilibrium temperature of TIC 183374187 b is about 1,379 K (1,106 °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 TIC 183374187 b — one full orbit around TIC 183374187 — lasts 5.06 Earth days, shorter than Mercury's 88-day year. Its orbit is highly elliptical (eccentricity 0.51), swinging dramatically closer to and farther from its star.
How Was TIC 183374187 b Discovered?
TIC 183374187 b was discovered in 2026 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 TIC 183374187 b?
TIC 183374187 b is 3,942.4 light-years (1,208.8 parsecs) from Earth. Light arriving here tonight left the planet about 3,942 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 69,386,240 years to make the journey.

Frequently Asked Questions About TIC 183374187 b
Is TIC 183374187 b habitable?
TIC 183374187 b is not known to orbit within the habitable zone of TIC 183374187, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is TIC 183374187 b?
TIC 183374187 b is about 3,942 light-years from Earth in the constellation Phoenix. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 69,386,240 years to get there.
How big is TIC 183374187 b compared to Earth?
TIC 183374187 b has 14.03 times the radius of Earth and about 178 times its mass.
How long is a year on TIC 183374187 b?
One orbit around TIC 183374187 takes 5.1 Earth days — short enough that 72 of its years would fit into one Earth year.
