HD 210277 [SEP] constellation
HD 210277
HD 210277 is a 7th magnitude star in the constellation of Aquarius. It is a yellow dwarf star (spectral type G0V) with a mass around 0.92 times that of our Sun. Since its distance is about 70 light years, it is not visible to the unaided eye. With binoculars it is easily visible.
The star has a extrasolar planet that has a minimum mass greater than Jupiters orbiting it in 442 days. Claims were made in 1999 that a dust disk around the star HD 210277, similar
HD 210277 b
HD 210277 b is an extrasolar planet orbiting the star HD 210277. It was discovered in September 1998 by the California and Carnegie Planet Search team using the highly successful radial velocity method. The planet is at least 24% more massive than Jupiter. The mean distance of the planet from the star is slightly more than Earth's distance from the Sun. However, the orbit is very eccentric, so at periastron this distance is almost halved, and at apastron it is as distant as Mars is from the
