How far away is the Andromeda galaxy from ours?
about 2.5 million light-years
Currently, Andromeda and the Milky Way are about 2.5 million light-years apart.
How far is the Andromeda Galaxy our closest galaxy across?
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 with diameter of about 220,000 ly approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest large galaxy to the Milky Way.
How far away is the Andromeda galaxy right now?
Remember, though, that the Andromeda Galaxy is 2.2 million light-years away, with a single light-year being almost 10 trillion kilometers (6 trillion miles). So although it does appear that this galaxy is approaching our Milky Way galaxy… it’s nothing to lose sleep over.
How long will it take for the Andromeda galaxy to hit us?
roughly 4.5 billion years
In roughly 4.5 billion years’ time the Milky Way will smash into the rapidly approaching Andromeda Galaxy, and astronomers are still attempting to predict what it will be like when the two galaxies collide. That a collision between our galaxy and the Andromeda Galaxy is inevitable has been known for a little while.
Will humans survive Andromeda collision?
Luckily, experts think that Earth will survive, but it won’t be entirely unaffected. The collision will unfold right in front of us, changing the night sky to look like nothing any human has seen before.
What is the closest galaxy to the United States?
the Canis Major Dwarf Galaxy
Distance Information 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.
What are the 3 closest galaxies to the Milky Way?
|1||Milky Way Galaxy||0|
|2||Canis Major Dwarf||0.025 Mly|
|3||Virgo Stellar Stream||0.030 Mly|
|4||Sagittarius Dwarf Elliptical Galaxy||0.081 Mly|
Is Andromeda Galaxy moving toward us?
Based on Doppler shifting of its light, Andromeda is speeding toward us at 68 miles per second (110 kilometers per second). Compare this to the light from Andromeda, which is moving toward us at 186,000 miles per second (300,000 km/s).
Can the earth survive an Andromeda collision?
Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 3.75 billion years due to gradually increasing luminosity of the Sun (it will have …
How much longer until the sun dies?
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. One way or another, humanity may well be long gone by then.
