Which is the smallest galaxy in universe?
Scientists at the University of California at Irvine have discovered a galaxy so small that it barely even qualifies as a galaxy. Deemed
“Segue 2
,” the dwarf galaxy only contains about 1,000 stars and is the least massive galaxy in the known universe, reports Phys.org.
Are there tiny galaxies?
There are
many dwarf galaxies in the Local Group
; these small galaxies frequently orbit larger galaxies, such as the Milky Way, the Andromeda Galaxy and the Triangulum Galaxy. A 2007 paper has suggested that many dwarf galaxies were created by galactic tides during the early evolutions of the Milky Way and Andromeda.
What are the smallest galaxies called?
The smallest independent structures known today are
Segue 1 and Segue 3
. Only approximately 1000 stars are present in the entirety of dwarf galaxies Segue 1 and Segue 3,…

What is the smallest thing in the universe?
Quarks
are among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can't be observed outside of their respective hadrons.
How many galaxies are in space?
Several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain
200 billion to two trillion galaxies
.
How small can a galaxy get?
Hubble Helps Find Smallest Known Galaxy Containing a Supermassive Black Hole. … It is inside one of the densest galaxies known to date — the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of
about 300 light-years
, which is only 1/500th of our galaxy's diameter.
What galaxy do we live in?
We live in one of the arms of a large spiral galaxy called
the Milky Way
. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre. 100 000 years to cross from one side to the other.
What is the biggest star?
The cosmos is full of objects that defy expectations. Although it's difficult to pin down the exact traits of any given star, based on what we know, the largest star is
UY Scuti
, which is some 1,700 times as wide as the Sun.
Is star bigger than the galaxy?
Our Sun
is just one star among the hundreds of billions of stars in our Milky Way Galaxy. … The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
What is the oldest spiral galaxy?
The most ancient spiral galaxy found so far, called
BRI 1335-0417
, at an distance of 12.4 billion light-years and at a time just 1.4 billion years after the Big Bang. Spiral arms are visible on both sides of the compact, bright area in the galaxy center.
What arm do we live in?
In recent decades, research advances have revealed that we live in our very own spiral arm of the galaxy, albeit a relatively minor one. Our spiral arm is formally called
the Orion-Cygnus Arm
. It's also known simply as the Orion Arm or Local Arm, and you sometimes still hear the names Orion Bridge or Orion Spur.
