Explanation:
Detailed explanation-1: -5−3754 is thought to have formed in a supernova explosion of its companion star about one million years ago and is moving across the sky at 108 km/s. It was discovered in 1992, and observations in 1996 confirmed that it is a neutron star, the closest to Earth discovered to date.
Detailed explanation-2: -Known as RX J1856. 5-3754, it measures only 20 km across. Although it is unusually hot for its age, about 700, 000 °C, earlier observations did not reveal any activity at all, contrary to all other neutron stars known so far.
