WISPIT 2 c
WISPIT 2 c is a hot Jupiter orbiting WISPIT 2 in the constellation Aquila. It lies about 440 light-years from Earth and was discovered in 2026 using the imaging method.
How Big Is WISPIT 2 c?
WISPIT 2 c has a radius of 17.93 times that of Earth, or 1.60 times the radius of Jupiter. Its mass is 3,178 times that of Earth.
Is WISPIT 2 c in the Habitable Zone?
WISPIT 2 c orbits beyond the outer edge of the habitable zone of WISPIT 2. At that distance, any surface water would almost certainly be frozen.
Habitable zone of WISPIT 2: 0.671–1.665 AU (conservative: 0.850–1.579 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on WISPIT 2 c
The equilibrium temperature of WISPIT 2 c is about 2,050 K (1,777 °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
WISPIT 2 c orbits at an average distance of 14.000 AU.
How Was WISPIT 2 c Discovered?
WISPIT 2 c was discovered in 2026 using the imaging method, with observations from Multiple Observatories.
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 WISPIT 2 c?
WISPIT 2 c is 440.0 light-years (134.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1586. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 7,744,000 years to make the journey.

Frequently Asked Questions About WISPIT 2 c
Is WISPIT 2 c habitable?
No — WISPIT 2 c orbits outside the habitable zone of WISPIT 2 and is likely too cold for liquid water on its surface.
How far away is WISPIT 2 c?
WISPIT 2 c is about 440 light-years from Earth in the constellation Aquila. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 7,744,000 years to get there.
How big is WISPIT 2 c compared to Earth?
WISPIT 2 c has 17.93 times the radius of Earth and about 3,178 times its mass.
