Larawag — Star in Scorpius
HIP 82396; Epsilon Scorpii; 26 Scorpii
About Larawag
Description
Epsilon Scorpii (no widely used proper name) is an orange giant of spectral type K2.5III at magnitude 2.29, located about 65 light-years from Earth. It sits in the body of Scorpius, between the head and the tail. With a surface temperature of roughly 4,600 K and a luminosity about 72 times solar, it is a fairly typical evolved giant star.
Observing Tips
Located in the central body of Scorpius, Epsilon Sco lies between the bright stars Antares and Shaula. Its warm orange color complements the deep red of nearby Antares. It is best observed during summer months (June through August) from the northern hemisphere, or during the southern winter. From mid-northern latitudes, Scorpius is always low on the southern horizon.
History
Epsilon Scorpii has no traditional proper name, though it was occasionally called Wei in Chinese astronomy, meaning 'the tail.' It was part of various asterisms in different cultural traditions. Its position in the body of the Scorpion has made it a reliable reference point for mapping the constellation since antiquity.
Fun Facts
At only 65 light-years away, Epsilon Scorpii is one of the closest giant stars to our solar system. It is also one of the closest K-type giants visible to the naked eye, making it a good example of what the Sun may look like in about 5 billion years when it becomes a red giant.
