Stars and planets have some things in common. They are both accumulations of mass. Both have gravity and respond (move) in accordance with gravimetric laws. They both are generally round. They are both "building blocks" of a loose galactic structure. Planets are the building blocks of a star system (they orbit a star) and stars are the building blocks of a local galactic cluster (a group of nearby stars) or a galaxy itself. They are also made with the same gas.
they all are in space?
All of them have stars and space dust for sure.
I think the least common is elliptical or irregular..
there are as many galaxies as their is grains of sand all over earth and mars so it really does not matter but the answer:spiral but the least common is oval
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
In theory, all galaxies originate from the Big Bang, which is the name that describes the explosion that propelled all matter into the cosmos. All galaxies are moving. All galaxies produce energy like light and gravity. Think of galaxies like you would human beings. Although very different in some ways, they are mostly the same.

All stars and galaxies are in the universe.

There is a lot of doubt about the answer to this question. Depending on the sources, it could be spiral or elliptical.The most common type of galaxy is a dwarf galaxy.Of the main types of galaxies:Within our "local area" spiral galaxies are the most common with anywhere between 60 -> 75% of all galaxies. Ellipticals account only for 3 -> 20% whereas Irregular account for 5 -> 25%.Confused? You should be.The problem with the data is that it doesn't stipulate the area involved. Most percentages and answers are related to our local area and not the whole Universe. Also, as the most common type of galaxy is a dwarf elliptical galaxy, they use this as an Elliptical galaxy.Also, as observation data on far away galaxies is a record of what they were then, not what they are now.So: A dwarf elliptical galaxy is the most common type of galaxy, and a Spiral galaxy is the most common type of main galaxy.Locally Main- Spiral galaxies are more common making up about 60% of all galaxies, whereas elliptical galaxies only account for about 10 - 15%
They make up approximately two thirds of all known spiral galaxies.
They all contain some form of sphere (ball)
