1SWASP J140747.93−394542.6 (also known as 1SWASP J140747 , J1407 and Mamajek's Object ) is a star similar to the Sun in the constellation Centaurus at a distance of about 434 light-years from Earth. [5] [6] A relatively young star, its age is estimated to be 16 million years, and its mass is about 90% that of the Sun. [2] [7] The star has an apparent magnitude of 12.3 and requires a telescope to be seen. [3] The star's name comes from the SuperWASP ( Wide Angle Search for Planets ) program and the star's coordinates. The star is variable due to the planet orbiting around it and has been given the variable star designation V1400 Centauri . In 2007, J1407 was observed to be eclipsed and orbited by at least one major body, 1SWASP J1407b [8] ( J1407b ), thought to be either a large gas giant planet or a brown dwarf, with an immense ring system.
