At a distance of 0.46 astronomical units (AU, or the Earth-Sun distance) to its star, the planet Halla resembles "warm" or "hot" Jupiter-like planets that are thought to have started on larger orbits before migrating inward close to their stars. The result is a red giant, which would appear more orange than red. Because of this constant churning, red dwarfs can steadily burn through their entire supply of hydrogen over trillions of years without changing their internal structures, unlike other stars. A lone brown dwarf, no known planets orbit this object. But okay, let me explain from the very beginning. ], - Distance from the sun: 14.84 light-years - Discovered in: 1995, GJ 1061 resides in a constellation in the southern sky, Horologium, or the clock. This three-star system can be seen from Earth, but Proxima Centauri is a bit too dim for the naked eye to detect. The collapsed stars more powerful gravity can begin to drain away material from the companion star if it orbits closely enough. After another few million years, radiation from the young Sun and nearby stars dispersed the disks remaining gas, leaving behind only solid objects, which continued to collide, shatter, and merge to form the planets, asteroids, and other bodies we see today. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it. If you have a telescope at home, though, you can see solitary white dwarfs LP 145-141 in the southern constellation Musca and Van Maanens star in the northern constellation Pisces.
