If the object SOri70 really is a planet 36, 000 times as far as Jupiter or 180, 000 times as far as the Earth from the next star Sigma Orionis is like Jupiter or the Earth from the sun, then the researchers would have to seek an explanation of how it originated or drifted there. Alternatively, SOri70 could also be a brown dwarf who just happened to get in the line of sight between Earth and Sigma Orionis. The probability for the second alternative, the astronomers at 20 percent.
The decision between the two alternatives depends on a precise distance determination. Here astronomers hope for the help of the Hubble Space Telescope. The previous recordings were made with the Keck Observatory in Hawaii and with the William Herschel Telescope in the Canary Islands.
Besides Spanish astronomers and astronomers from the University of Hawaii, Joachim Eislöffel from the Thüringer Landessternwarte and Reinhold Mundt from the Max Planck Institute for Astronomy also participated in the discovery of SOri70. displayAxel Tilleman
