HD 92945
HD 92945 is a K-type main sequence star in the constellation of Hydra. Its apparent visual magnitude varies by 0.02 magnitudes and is approximately 7.72 at maximum brightness.
In 2007, a debris disk with estimated dust mass 0.047±0.003 M🜨 has been observed around the star by coronagraphic imaging, using the ACS and NICMOS instruments on the Hubble Space Telescope. It appears to extend 45 to 175 astronomical units from HD 92945.
The disk has a gap at radius 73±3 AU which may be carved by the planet, but no planet with mass exceeding 1-2 MJ was observed in the gap.
Evidence for a planet via astrometric observations was presented in 2024.
