NGC 3115 (also called the Spindle Galaxy or Caldwell 53) is a field lenticular (S0) galaxy in the constellation Sextans. The galaxy was discovered by William Herschel on February 22, 1787. [4] [5] At about 32 million light-years away from Earth, it is several times bigger than the Milky Way.

NGC 3115，也稱為 紡錘星系 或 科德韋爾53，是位於 六分儀座 的一個 透鏡星系。 這個星系是 威廉·赫歇爾 在1787年2月22日發現的 [3]，與 地球 的距離大約是3,200萬 光年，它的大小數倍於 銀河系。 在1992年， 夏威夷大學 的John Kormendy和 密西根大學 的Douglas Richstone宣稱在這個星系觀測到 超大質量黑洞 [4]，它是當時發現最大的 (20億 太陽質量)。 這個星系的 恆星 看起來都是老年或是不活躍的， 黑洞 的生長也已經停止。 NGC 5866 - 另一個經常會與紡錘星系做比 …

2011年7月27日 · NGC 3115 is located about 32 million light years from Earth and is classified as a so-called lenticular galaxy because it contains a disk and a central bulge of stars, but without a detectable spiral pattern.

NGC 3115，也称为纺锤星系或科德韦尔53，是位于六分仪座的一个透镜星系。 这个星系是威廉·赫歇尔在1787年2月22日发现的，与地球的距离大约是3,200万光年，它的大小数倍于银河系。

NGC 3115 is a Elliptical/Spiral Galaxy in the Sextans constellation. NGC 3115 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

2023年8月9日 · C53 is perhaps most notable for the supermassive black hole that lurks at its center; astronomers estimate that it has a mass roughly one billion times the mass of our Sun. This means C53 hosts the closest billion-solar-mass black hole to Earth.

NGC 3115 is a lenticular galaxy that we see edge-on. It lacks spiral arms but boasts a galactic bulge and prominent disk. It hosts an elderly stellar population and has used up nearly all of its star-forming material. It is located about 32 million light-years away.

NGC 3115 is a Lenticular Galaxy located in the constellation of Sextans in the equatorial region. NGC 3115's distance from Earth is 33,525,614.06 light years. NGC 3115 is called NGC 3115 in the New General Catalogue (NGC).

2023年4月8日 · NGC 3115 is an edge-on lenticular galaxy in Sextans. Lenticular galaxies are similar to spiral galaxies in that they in the form of a broad, thin disk, however, the disk of a lenticular galaxy is smooth and relatively featureless without any clear spiral structure.

NGC 3115 is located about 32 million light years from Earth and is classified as a so-called lenticular galaxy because it contains a disk and a central bulge of stars, but without a detectable spiral pattern.
