The Milky Way is approximately 890 billion to 1.54 trillion times the mass of the Sun in total (8.9 × 10 11 to 1.54 × 10 12 solar masses), [7] [8] [9] although stars and planets make up only a small part of this. Estimates of the mass of the Milky Way vary, depending upon the method and data used.
Planet d, the outermost confirmed planet, is a Jupiter-sized planet which orbits in the habitable zone. [99] Radial velocity measurements discovered an additional signal, which could be a fourth planet or a stellar companion.

The term "The Local Group" was introduced by Edwin Hubble in Chapter VI of his 1936 book The Realm of the Nebulae. [11] There, he described it as "a typical small group of nebulae which is isolated in the general field" and delineated, by decreasing luminosity, its members to be M31, Milky Way, M33, Large Magellanic Cloud, Small Magellanic Cloud, M32, NGC 205, NGC 6822, NGC 185, IC 1613 and ...
Size (left) and distance (right) of a few well-known galaxies put to scale. There are an estimated 100 billion galaxies in all of the observable universe. [1] On the order of 100,000 galaxies make up the Local Supercluster, and about 51 galaxies are in the Local Group (see list of nearest galaxies for a complete list).

The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 ...
Largest Galaxy in the Local Group (The Milky Way is the second largest), with at least 19 satellite galaxies. Barred spiral galaxy. 152,000 ly 87
There could be 300 million planets in the Milky Way Galaxy that support life, according to NASA estimates. The planets are all rocky, similar in size to Earth and orbit in the “Goldilocks zone ...
