HD 100546 is a star 337.3 LY from Earth. It is orbited by an approximately 20 Mj planet at 6.5 AU.[4]
frookie nd bennett r the best yas ==HD 100546 B== Evidence for a planetary companion to HD 100546 was gathered using the UVES echelle spectrograph at the VLT in Chile.[4] This confirms other data indicating a planetary companion. The planets size puts it near the border between a giant planet and a brown dwarf.[4]
Protoplanetary material
Spectroscopic analysis of mid-IR data taken from OSCIR on the 4 m Blanco Telescope at Cerro Tololo Inter-American Observatory indicates the presence of a small particles (10 - 18 ) containing silicates.[2] The material is found at distances out to 17 AU away from the star and has a temperature of approximately 227 K.[2]
