description 47 Ursae Majoris b Overview
47 Ursae Majoris b is a gas giant exoplanet orbiting the Sun-like G-type star 47 Ursae Majoris at a distance of approximately 2.1 astronomical units. Discovered in 1996 through radial velocity measurements, it was among the first known long-period exoplanets orbiting a Sun-like star. The planet has a minimum mass approximately 2.5 times that of Jupiter and follows a nearly circular orbit with a period of about 6 years. Additional planets were later identified in the same system.
help 47 Ursae Majoris b FAQ
What is 47 Ursae Majoris b?
47 Ursae Majoris b is a gas giant orbiting the G-type star 47 Ursae Majoris. Its orbit is around 2.1 astronomical units from the star, making it a relatively long-period planet compared with many early exoplanet discoveries.
When was 47 Ursae Majoris b discovered?
The planet was discovered in 1996 using radial-velocity observations. It was among the first known long-period exoplanets orbiting a Sun-like star.
How far is 47 Ursae Majoris b from Earth?
The 47 Ursae Majoris system is in the constellation Ursa Major and is roughly 46 light-years away. The planet itself is not directly seen as a separate bright object from Earth.
Is 47 Ursae Majoris b similar to Jupiter?
It is a gas giant with a Jupiter-like role in its planetary system, but its orbit is farther out than Jupiter's roughly 5.2 astronomical units. Its minimum mass and orbital properties are measured mainly through the motion of its host star.
