Hi guys It’s me, Antony…
Today I’m going to write about
The Smallest Blackhole found to date…
So guys Segue 2 is a dwarf spheroidal galaxy located in Constellation Aries. It was discovered in 2009 in the data obtained by Sloan Digital Sky Survey.
The galaxy is located at a distance of about 114,000 light-years away and moves towards the Sun at a speed of 40 kilometers per second. It is classified as a dwarf spheroidal galaxy that is approximately round in shape with a half-light radius of about 34 parsecs. The mass of the galaxy — about 550,000 solar masses
The galaxy consists of just 1,000 or so stars with a bit of dark matter holding them together. It is also one of the faintest known galaxies with light output just 900 times that of the Sun. That’s minuscule compared to the Milky Way, which shines 20 billion times brighter.
The stellar population of Segue 2 consists mainly of old stars formed more than 12 billion years ago. The metallicity of these old stars is also very low, which means that they contain at least 100 times less heavy elements than the Sun.
The stars of Segue 2 were probably among the first stars to form in the universe. Currently, there is no star formation in Segue 2.
