What is the size of a elliptical galaxy?

Answer 1

An elliptical galaxy is a galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. The galaxies range in shape from nearly spherical to highly flattened and have hundreds of millions to over one trillion stars.

Answer 2

The size of an elliptical galaxy can vary a great deal, though the largest galaxies are giant ellipticals, thought to form through collisions of several smaller galaxies. They can grow to enormous sizes.

A dwarf elliptical galaxy may be only a few thousand light years across and contain only a few billion stars, while a giant elliptical galaxy may be 3-5 million light years across and contain trillions of stars.

Answer 3

Our own galaxy (the "Milky Way") is a spiral galaxy, and has about 100,000 light-years across. If you prefer that in kilometers or meters, each light year is roughly 1013 km., or 1016 meters. Other galaxies may be larger or smaller, but that would be the approximate size.

Answer 4

An elliptical galaxy is a type of galaxy that has an elliptical shape rather than spiral shape. It has been suggested that this shape is due to a collision between two spiral galaxies.

Answer 5

Elliptical. To view actual images, I suggest you go to Google images, or the Wikipedia article, and search for "elliptical galaxy".

Answer 6

it looks like a circle seen slightly on edge

Answer 7

An elliptical galaxy has - well - an elliptical shape.

Much like an American football, a Rugby ball or an egg.

Answer 8

an elliptical galaxy looks a little bit like a circle

Answer 9

An elliptical galaxy is mainly composed of older low mass stars.

Answer 10

According to Wikipedia, the largest ones may have a diameter of over 100 kiloparsec - that is over 300,000 light-years.
