HD 126053

HD 126053 is a yellow dwarf star located approximately 166 light-years away from Earth in the constellation Virgo. It is a main-sequence star, similar in spectral type (G1V) and temperature to our Sun, though slightly older and more massive.

The star has been the subject of significant astronomical study due to the confirmed presence of at least one extrasolar planet orbiting it. This planet, designated HD 126053 b, is a hot Jupiter, a gas giant with a mass several times that of Jupiter and an extremely short orbital period. The planet's proximity to its star results in very high temperatures and rapid orbital speeds.

The discovery of HD 126053 b was made using the radial velocity method, which detects subtle variations in a star's motion caused by the gravitational pull of an orbiting planet. Further observations and studies have refined our understanding of the planet's characteristics and its orbital parameters. The star's relatively high metallicity (abundance of elements heavier than hydrogen and helium) has been noted, potentially influencing the formation and characteristics of its planetary system. The HD 126053 system continues to be an object of interest for astronomers studying exoplanets and planetary formation.
