'''Grup Lokal''' adalah sebuah grup galaksi |
'''Grup Lokal''' adalah sebuah [[grup galaksi]] yang dekat dengan [[Galaksi Bima Sakti]], yaitu [[Galaksi Andromeda]] dan [[Galaksi Triangulum]] beserta lebih dari 50 galaksi-galaksi kecil. Ukurannya kurang lebih 10 juta [[tahun cahaya]] dan diperkirakan total massa grup galaksi ini adalah 1,29 milliar [[massa matahari]]. Pusat massanya diperkirakan terletak diantara Bima Sakti dan Andromeda. |
||
[[Bima Sakti]], dan [[Galaksi Andromeda]], yang merupakan dua anggota besar grup galaksi ini, keduanya memiliki sistem satelit galaksi yang diperhitungkan sebagai anggota Grup Lokal. |
|||
== Sejarah == |
|||
Grup lokal pertama kali diidentifikasikan oleh Astronom [[Edwin Powell Hubble]] dalam bukunya ''The Realm of Nebulae''. Tetapi karena Hubble tidak tahu bahwa mereka adalah galaksi yang jauh, terpisah dari Bima Sakti, jadi Hubble memanggilnya sebagai [[nebula]] |

Grup Lokal adalah sebuah grup galaksi yang dekat dengan Galaksi Bima Sakti, yaitu Galaksi Andromeda dan Galaksi Triangulum beserta lebih dari 50 galaksi-galaksi kecil. Ukurannya kurang lebih 10 juta tahun cahaya dan diperkirakan total massa grup galaksi ini adalah 1,29 milliar massa matahari. Pusat massanya diperkirakan terletak diantara Bima Sakti dan Andromeda.
Bima Sakti, dan Galaksi Andromeda, yang merupakan dua anggota besar grup galaksi ini, keduanya memiliki sistem satelit galaksi yang diperhitungkan sebagai anggota Grup Lokal.
Sejarah
[sunting | sunting sumber]Grup lokal pertama kali diidentifikasikan oleh Astronom Edwin Powell Hubble dalam bukunya The Realm of Nebulae. Tetapi karena Hubble tidak tahu bahwa mereka adalah galaksi yang jauh, terpisah dari Bima Sakti, jadi Hubble memanggilnya sebagai nebula
