Sobre C42
Descrição
NGC 7006 is a globular cluster in Delphinus, about 135,000 light-years from Earth. It is one of the most distant globular clusters in the Milky Way's halo, lying well beyond the main body of the galaxy.
Dicas de Observação
A small, faint, unresolved glow in an 8-inch telescope. Appears stellar at low power. It cannot be resolved into individual stars with amateur telescopes due to its great distance. Best in summer and autumn evenings.
História
Discovered by William Herschel on August 21, 1784. Its extreme distance and retrograde orbit suggest it may have been captured from a dwarf galaxy long ago.
Curiosidades
NGC 7006 has a retrograde orbit around the Milky Way, moving opposite to the galaxy's rotation. This retrograde motion supports the theory that it originated in a satellite galaxy that was consumed by the Milky Way.
