SWEEPS-11 b
SWEEPS-11 b is a hot Jupiter orbiting SWEEPS-11 in the constellation Sagittarius. It was discovered in 2006 using the transit method.
How Big Is SWEEPS-11 b?
SWEEPS-11 b has a radius of 12.67 times that of Earth, or 1.13 times the radius of Jupiter. Its mass is 3,083 times that of Earth.
Is SWEEPS-11 b in the Habitable Zone?
The position of SWEEPS-11 b relative to the habitable zone of SWEEPS-11 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on SWEEPS-11 b — one full orbit around SWEEPS-11 — lasts just 43.1 hours, shorter than Mercury's 88-day year. It orbits at an average distance of 0.030 AU — closer to its star than Mercury is to the Sun.
How Was SWEEPS-11 b Discovered?
SWEEPS-11 b was discovered in 2006 using the transit method, with observations from Hubble Space Telescope.
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.

Frequently Asked Questions About SWEEPS-11 b
Is SWEEPS-11 b habitable?
SWEEPS-11 b is not known to orbit within the habitable zone of SWEEPS-11, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How big is SWEEPS-11 b compared to Earth?
SWEEPS-11 b has 12.67 times the radius of Earth and about 3,083 times its mass.
How long is a year on SWEEPS-11 b?
One orbit around SWEEPS-11 takes 1.8 Earth days — short enough that 203 of its years would fit into one Earth year.
