Is CHXR 73 b in the Habitable Zone?

The position of CHXR 73 b relative to the habitable zone of CHXR 73 cannot be precisely determined from the available orbital data.

Orbit and Year Length

CHXR 73 b orbits at an average distance of 210.000 AU.

How Was CHXR 73 b Discovered?

CHXR 73 b was discovered in 2006 using the imaging method, with observations from Hubble Space Telescope.

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 CHXR 73 b?

CHXR 73 b is 620.9 light-years (190.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1406. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 10,927,840 years to make the journey.
