Photos: Weird and wonderful planets beyond our solar system. A more precise animation would show that the distance of an object with a parallax angle of 1 arcsecond is 3.26 light-years, which astronomers call a parsec (short for "parallax second"). Castor has an apparent magnitude of 1.93. Answer (1 of 4): Good question, Light year is a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 10^12 km (nearly 6 million million miles). An early success of GPIES was the discovery of 51 Eridani b in December 2014, a planet about two-and-a-half times more massive than Jupiter, and orbiting just beyond the distance Saturn orbits our own Sun. Propus. THE STAR. Until now, astronomers have found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all of them less than about 3,000 light-years from Earth. Despite its “alpha” designation, it shines as Draco’s fourth-brightest star. Like most open star clusters, the stars in the cluster are slowly moving apart. Bellatrix is closer at 243 light years, fainter at … The most prominent are two A-class main-sequence stars that have red dwarf companions. Struve 2398 is only 11.52 light years distant. Between Propus and the Tejat Posterior, we can find the Jellyfish Nebula (IC 443, Sharpless 248), a supernova remnant. However, it is actually made up of six stars, or three pairs of stars (a sextuple star system). Rigel is 777 light years away and 51 000 times as bright as the Sun. 51 Pegasi is only 11% more massive than our Sun, and its radius is only 23% greater than our Sun’s. 51 Pegasi has physical properties (luminosity and temperature, for example) very similar to … A galaxy is considered a system that features numerous solar systems, stars, black holes, planets, and moons.
