HD 207129 is a G-type pre-main-sequence star in the constellation of Grus. It has an apparent visual magnitude of approximately 5.58. This is a Sun-like star with the same stellar classification G2V and a similar mass. It is roughly the same age as the Sun, but has a lower abundance of elements other than hydrogen and helium; what astronomers term the star's metallicity.
A debris disk has been imaged around this star in visible light using the ACS instrument on the Hubble Space Telescope; it has also been imaged in the infrared (70 μm) using the MIPS instrument on the Spitzer Space Telescope. Based on the ACS image, the disk appears to have a radius of about 163 astronomical units and to be about 30 AU wide, and to be inclined at 60° to the plane of the sky.[1]
Another star, CCDM J21483-4718B (also designated CD−47 13929 or WDS J21483-4718B), of apparent visual magnitude 8.7, has been observed 55 arcseconds away from this star,[2] but based on comparison of proper motions, it is believed to be an optical double and not physically related to its companion.[3]
