43 Camelopardalis is a single[9] star in the northern circumpolar constellation of Camelopardalis,[8] located roughly 1,060 light years away from the Sun based on parallax.[1] It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of 5.11.[2] This object is moving closer to the Earth with a heliocentric radial velocity of −21 km/s.[4]
The stellar classification of 43 Camelopardalis is B7 III,[3] matching that of a blue giant. It is spinning rapidly with a projected rotational velocity of 190 km/s.[7] The star has five[5] times the mass of the Sun and about 4.4[6] times the Sun's radius. It is radiating 724[7] times the luminosity of the Sun from its photosphere at an effective temperature of 13,183 K.[7]
Chinese name
[edit | edit source]In Chinese, 紫微右垣 (Zǐ Wēi Yòu Yuán), meaning Right Wall of Purple Forbidden Enclosure, refers to an asterism consisting of 43 Camelopardalis, α Draconis, κ Draconis, λ Draconis, 24 Ursae Majoris, α Camelopardalis and BK Camelopardalis.[10] Consequently, 43 Camelopardalis itself is known as 紫微右垣五 (Zǐ Wēi Yòu Yuán wǔ, English: the Fifth Star of Right Wall of Purple Forbidden Enclosure.),[citation needed] representing 上衛 (Shǎngwèi), meaning First Imperial Guard.[11] 上衛 (Shǎngwèi) is westernized into Shang Wei by R.H. Allen, the meaning is "Higher Guard", but it is not cleared designation[12]
