HD 95808 is a double star in the constellationofCrater. Its apparent magnitude is 5.50,[2] but interstellar dust makes it appear 0.11 magnitudes dimmer than it should be.[4] It is located some 340 light-years (104 parsecs) away, based on parallax.[1]
HD 95808 is a G-type giant star. At an age of 680 million years old, it has swelled up to a radius of 10.1 times that of the Sun, and it is 2.43 times as massive. It emits 64.6 times as much energy as the Sun at a surface temperature of 5,029 K.[4]
