How far is it from the Milky Way to the Andromeda Galaxy?

How far is it from the Milky Way to the Andromeda Galaxy?

approximately 2.5 million light-years
The Andromeda Galaxy (IPA: /ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way.

How big is the Milky Way compared to Andromeda?

They were surprised to find that the Andromeda galaxy’s halo stretches much, much farther out beyond the visible boundaries of the galaxy than previously known. In fact, it extends as far as half the distance to our Milky Way (1.3 million light-years) and even farther in other directions (up to 2 million light-years).

How far away is the Andromeda Galaxy in light-years?

2.537 million light years
Andromeda Galaxy/Distance to Earth

What is the distance across the Andromeda Galaxy?

about 2,480,000 light-years
The Andromeda Galaxy is one of the few visible to the unaided eye, appearing as a milky blur. It is located about 2,480,000 light-years from Earth; its diameter is approximately 200,000 light-years; and it shares various characteristics with the Milky Way system.

What will happen when the Milky Way collides with the Andromeda Galaxy?

The result of the collision between Andromeda and the Milky Way will be a new, larger galaxy, but rather than being a spiral like its forebears, this new system ends up as a giant elliptical. The pair will end up forming a binary at the heart of the new, larger galaxy.

What does Milky Way look like from Andromeda?

Andromeda has an inclination angle of about 77° — meaning, as you said, we see it nearly edge-on. If those inhabitants also live in Andromeda’s stellar disk and near the center of the galaxy, the Andromedans would see the Milky Way at an inclination angle of about 68°, similar to our view of their galaxy.

How many galaxies are close to the Milky Way?

Scientists have known for some time that the Milky Way Galaxy is not alone in the Universe. In addition to our galaxy being part of the Local Group – a collection of 54 galaxies and dwarf galaxies – we are also part of the larger formation known as the Virgo Supercluster.

Can we travel to Andromeda Galaxy?

Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. Traveling to the Andromeda Galaxy, 2.54 million light years away, would take 28 years on-ship time with a constant acceleration of 1g and a deceleration of 1g after reaching half way, to be able to stop.

How does the Andromeda Galaxy compare with the Milky Way?

The Andromeda is a spiral galaxy, like the Milky Way, with widespread projections of stars entwined around a distinct center. One difference is that the Andromeda galaxy is larger than the Milky Way and emits more light. The galaxy is centered on a shining protuberance.

How many stars are between Milky Way and Andromeda?

Stellar collisions. While the Andromeda Galaxy contains about 1 trillion (10 12) stars and the Milky Way contains about 300 billion (3×10 11), the chance of even two stars colliding is negligible because of the huge distances between the stars.

What are facts about Andromeda Galaxy?

Andromeda Galaxy Facts. The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide and the result will be a giant elliptical galaxy.

What is the next closest galaxy to Andromeda?

Nearest major galaxy : Andromeda galaxy (spiral galaxy) – 2.5 million light-years. Triangulum Galaxy (spiral galaxy) – 2.73 million. Nearest Minor galaxiesCanis Major Dwarf galaxy (status as galaxy disputed) – about 25,000 light-years away. Sagittarius Dwarf Spheroidal Galaxy (elliptical) – about 70,000 light-years away. Large Magellanic Cloud – about 163,000 light-years.
