Most common type, most of these are dwarf galaxies (too small and too dim to be easily seen). Shaped like large, 3-dimensional ellipses (football shaped). Giant elliptical galaxies can be over 9 million light-years across and contain trillions of stars.. Dwarf elliptical galaxies- only about 3,000 light-years across and contain fewer than a million stars. Most contain little gas and dust and cannot make new stars. Irregular galaxies can take many different shapes and contain 100 million to 10 billion stars, Less common than elliptical or spiral. a. Larger than Dwarf ellipticals but smaller than spiral galaxies. a galaxy that does not have a regular shape, typically smaller than other types or galaxies, generally have bright, young stars and lots of gas and dust to form new stars.
Mainly due to the huge number of them and the large distances involved. Our galaxy, the milky way, is estimated to have around 200 billion stars, but this is only a guess. The â¦ re is a large central bulge in the middle of the galaxy which we can't see because of interstellar gas and dust in the way.he estimate for the number of stars is about 100 billion stars-plus or minus 50 billion. 2 people found this useful. 1  Easy to Use Pregnancy Due Date Calculators When you are pregnant, the question on everyone's mind is when the baby is due.
