CD-35 2722 b
CD-35 2722 b is a cold gas giant orbiting the M1 V star CD-35 2722 in the constellation Columba. It lies about 73 light-years from Earth and was discovered in 2011 using the imaging method.
How Big Is CD-35 2722 b?
CD-35 2722 b has a radius of 17.37 times that of Earth, or 1.55 times the radius of Jupiter. Its mass is 9,376 times that of Earth.
Is CD-35 2722 b in the Habitable Zone?
The position of CD-35 2722 b relative to the habitable zone of CD-35 2722 cannot be precisely determined from the available orbital data.
Orbit and Year Length
CD-35 2722 b orbits at an average distance of 67.000 AU.
How Was CD-35 2722 b Discovered?
CD-35 2722 b was discovered in 2011 using the imaging method, with observations from Gemini 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 CD-35 2722 b?
CD-35 2722 b is 73.0 light-years (22.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1953. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,284,800 years to make the journey.
