Question

What percentage light- Year away is that the closest galaxy to ours and what's it called?

Answer 1

Hint: A galaxy may be a collection of stars and planets that are held together by gravity. During a galaxy, the celestial bodies rotate around a central object. The Earth's galaxy is understood because of the Milky Way. Our system, made from the Sun and therefore the planets that encircle it, may be a tiny part of that galaxy.

Complete answer:
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest, at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
 The massive Magellanic Cloud, 1,690,000,000,000,000,000 km (179,000 light years) away, was once considered the closest galaxy outside of the Milky Way. The tiny Magellanic Cloud is 1,980,000,000,000,000,000 km (210,000 light years) away.
This is an inventory of known galaxies within 3.8 megaparsecs (12 million light-years) of the system, in ascending order of heliocentric distance, or the space to the Sun. This encompasses all of the about 50 major Local Group galaxies, and a few that are members of neighboring galaxy groups, the M81 Group and therefore the Centaurus A/M83 Group, and a few that are currently not in any defined galaxy group.

Note:
Several thousand galaxies, each consisting of billions of stars, are during this small view. XDF (2012) view: Each light speck may be a galaxy, a number of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to 2 trillion galaxies.
