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.
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.
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1] [2] Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which is almost exactly at the galactic rotational center.
As of 2020, S4714 is the current record holder of closest approach to Sagittarius A*, at about 12.6 astronomical units (1.88 × 10 9 km), almost as close as Saturn gets to the Sun, traveling at about 8% of the speed of light. These figures given are approximate, the formal uncertainties being 12.6 ± 9.3 au and 23 928 ± 8840 km/s. Its orbital ...
A moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or orbital elements of an astronomical object, because such quantities are subject to perturbations and change over time. The primary use of astronomical quantities specified by epochs is to calculate other relevant ...
It’s time to redefine your daily routines and responsibilities, Cancer. The sun in Sagittarius prompts you to address health, work habits and other obligations, but its square to Neptune can ...
The track includes the lyrics, “just twin fire signs, four blue eyes,” a nod to her and the element of her zodiac sign (fire signs include Aries, Leo and Sagittarius).
