Свойства:
Крупнейшая галактика Местной группы

Галактика Андромеды или Туманность Андромеды (M31, NGC 224) — спиральная галактика типа Sb. Эта ближайшая к Млечному Пути другая сверхгигантская галактика расположена в созвездии Андромеды и удалена от нас, по последним данным, на расстояние 772 килопарсек (2,52 млн световых лет). Плоскость галактики наклонена к нам под углом 15°, её видимый размер — 3,2°, видимая звёздная величина — +3,4m.

Галактика Андромеды в ультрафиолетовых лучах.

Галактика Андромеды имеет массу в 1,5 раза больше Млечного Пути и является самой большой в Местной группе: по существующим в настоящее время данным, в состав Галактики (Туманности) Андромеды входит около триллиона звёзд. У неё есть несколько карликовых спутников: M32, M110, NGC 185, NGC 147 и, возможно, другие. Её протяжённость составляет 260000 световых лет, что в 2,6 раза больше, чем у Млечного Пути. На ночном небе галактику Андромеды можно увидеть невооружённым глазом. По площади, для наблюдателя с Земли, она равна семи полным Лунам.
