Omega Serpentis

[2] Based upon an annual parallax shift of 11.93 mas as seen from Earth, it is located about 273 light years from the Sun.

[4] It is a member of the Ursa Major Stream, lying among the outer parts, or corona, of this moving group of stars that roughly follow a common heading through space.

[7] With an estimated age of around four billion years,[4] Omega Serpentis is an evolved G-type giant star with a stellar classification of G8 III.

[3] It is a red clump giant, which means that it is generating energy at its core through the nuclear fusion of helium.

It is radiating 69 times the solar luminosity from its photosphere at an effective temperature of 4,797 K.[4] Observations made between 2001 and 2003 by the Okayama Planet Search Program showed that Omega Serpentis is undergoing periodic radial velocity variations with a preliminary period estimate of 312.3 days.
