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 ...
Galactic Tick Day is an awareness and education day that celebrates the movement of the Solar System around the Milky Way galaxy. [1] [2] [3] [4]The day occurs at a regular interval of 1.7361 years (or 633.7 days), [5] which is called a galactic tick.
The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. [1] One galactic year is approximately 225 million Earth years . [ 2 ]

A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
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.
