MWC 758 c
MWC 758 c is a exoplanet orbiting the A8Ve star MWC 758 in the constellation Taurus. It lies about 520 light-years from Earth and was discovered in 2023 using the imaging method.
Is MWC 758 c in the Habitable Zone?
The position of MWC 758 c relative to the habitable zone of MWC 758 cannot be precisely determined from the available orbital data.
Temperature on MWC 758 c
The equilibrium temperature of MWC 758 c is about 500 K (227 °C) — hotter than anywhere on Earth. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
MWC 758 c orbits at an average distance of 100.000 AU.
How Was MWC 758 c Discovered?
MWC 758 c was discovered in 2023 using the imaging method, with observations from Large Binocular Telescope Observatory.
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 MWC 758 c?
MWC 758 c is 520.3 light-years (159.5 parsecs) from Earth. Light arriving here tonight left the planet around the year 1506. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 9,157,280 years to make the journey.
