What Am I ?

The Andromeda galaxy (Messier 31,
M31 or NGC 224) is a spiral galaxy
about 2.5 million light years from Earth.
When Was I Made?

According to astronomers, Andromeda
was formed out of the collision of two
smaller galaxies 5-9 billion years ago
Where Can You Find Me?

Andromeda is the nearest spiral galaxy
to the Milky Way, but not the closest
overall

The Andromeda galaxy is in the
Andromeda constellation, named after
the mythological princess, Andromeda

Galaxy
How Big Am I ?

Andromeda is the largest galaxy of the
Local group, which has the Andromeda
Galaxy, the Milky Way, the Triangulum
Galaxy, and about 30 other smaller
galaxies

Andromeda is estimated to be to be
7.1x10 solar masses, and has about 1
trillion stars, more than in the Milky Way.

Can You See Me?

With an apparent magnitude ( measure
of brightness) of 3.4, the Andromeda
Galaxy is known to be one of the
brightest Messier objects (a set of
astronomical objects), making it visible
to the naked eye on moonless nights

It appears more than six times as wide
as the full Moon when photographed
through a large telescope, only the
bright centre is visible to the naked eye
,or when viewed using binoculars or a
small telescope
Collision With The Milky Way
The Andromeda Galaxy is approaching
the Milky Way at about 100 to 140 km
per second ,400 light years every million
years, making it one of the few blueshifted galaxies.
 The Andromeda Galaxy and the Milky
Way are expected to collide in about
4.5 billion years. A likely result of the
collision is that the galaxies will combine
to form a giant elliptical (egg shaped)
galaxy.

Collision With The Milky Way

The fate of the Earth and the Solar
system in the collision are currently
unknown. If the galaxies do not
combine, there is a small chance that
the Solar System could be forced away
from the Milky Way or join Andromeda
NGC 2207 and IC 2163 are an example of what a collision of galaxies looks like
