  2. Sagittarius A* - Wikipedia

    en.wikipedia.org/wiki/Sagittarius_A*

    Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.

  3. Sagittarius A - Wikipedia

    en.wikipedia.org/wiki/Sagittarius_A

    Sagittarius A (Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole. It is located between Scorpius and Sagittarius , and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.

  4. Sagittarius A* cluster - Wikipedia

    en.wikipedia.org/wiki/Sagittarius_A*_cluster

    The Sagittarius A* cluster is the cluster of stars in close orbit around Sagittarius A*, the supermassive black hole at the center of the Milky Way (in the Galactic Center). The individual stars are often listed as " S-stars ", but their names and IDs are not formalized, and stars can have different numbers in different catalogues .

  5. Galactic Center - Wikipedia

    The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope. [32] The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.

  6. S62 (star) - Wikipedia

    en.wikipedia.org/wiki/S62_(star)

    In addition, S62 has a highly eccentric orbit which makes it pass very close to Sgr A*, only 16 astronomical units (2.4 × 10 9 km), less than the distance between Uranus and the Sun. The star therefore passes only about 215 times the Schwarzschild radius of Sgr A* (the Schwarzschild radius of Sgr A* is approximately 0.082 AU, or 12 million km).

  7. S2 (star) - Wikipedia

    en.wikipedia.org/wiki/S2_(star)

    S2, also known as S0–2, is a star in the star cluster close to the supermassive black hole Sagittarius A* (Sgr A*), orbiting it with a period of 16.0518 years, a semi-major axis of about 970 au, and a pericenter distance of 17 light hours (18 Tm or 120 au) – an orbit with a period only about 30% longer than that of Jupiter around the Sun, but coming no closer than about four times the ...

  8. S4716 - Wikipedia

    en.wikipedia.org/wiki/S4716

    It orbits the Sgr A* in 4.0 years, on an elliptical orbit with an eccentricity of 0.75. Its closest approach to Sgr A* is 15 billion kilometers (about the distance to the space probe Voyager 2 in 2022, or three times the distance of Neptune from the Sun), while its farthest approach is 100 billion kilometers.

  9. Satellite galaxies of the Milky Way - Wikipedia

    The Sagittarius Dwarf Spheroidal Galaxy is currently in the process of being consumed by the Milky Way and is expected to pass through it within the next 100 million years. The Sagittarius Stream is a stream of stars in polar orbit around the Milky Way leeched from the Sagittarius Dwarf.
