Elliptical Galaxy!
The Milky way is a spiral galaxy.
a spiral galaxy
The Andromeda Galaxy is a spiral barred galaxy, similar to our own galaxy, the Milky Way.
Both are spiral galaxies.
Our solar system is tiny compared to the size of the galaxy. If we take the outer edge of the solar system to be the outer part of the Oort cloud, then it is about 2 light years in diameter. By comparison our galaxy is about 100,000 light years across. The size ratio is similar to that between a grain of sand and a football field.
Elliptical
Andromeda is a spiral galaxy, similar to our own.
To date, no galaxies are rectangular in shape.
It depends what shape the galaxy has.
A spiral galaxy or barred galaxy, the milky way is one.
Rugby balls are similar to a football in shape, but are slightly wider and bigger.
Oval.
An E0 galaxy, is part of the Hubble definitions for galaxies.E = Elliptical. 0 = It's shape - in this case like a round football (Soccer)See related link for more information
The shape of the Milky Way (our galaxy) is the shape of a spiral.
irregular galaxy
First of all, it's a spiral galaxy, not an spiral galaxy. Second, a spiral galaxy would have a spiral shape, obviously.
An Irregular Galaxy is a galaxy that has no shape or form as defined by the classes of the "Hubble sequence" An Amorphous galaxy is a galaxy that has neither spiral nor elliptical in shape as defined by "The Atlas of Peculiar Galaxies". See related links for pictorial representation
