A galaxy is a large group of stars that orbit around a common point usually a Supermassive Black Hole. Some galaxies, such as the dwarf Galaxy called Segue 2, do not have a Supermassive Black Hole but rather orbit a central gravitational point. The word galaxy comes from the French ...
The debate on the origin and nature of UCDs, and the recently discovered ultra-faint dwarf spheroidal (dSph) galaxies which contain very few stars, has motivated us to as the question 'What is a galaxy?' Our aim here is to promote further discussion of how to define a galaxy and, in ...
The Large Magellanic Cloud is a galaxy with a single spiral arm that orbits the Milky Way. With an estimated 30 billion stars, it is sometimes classified as a dwarf galaxy and sometimes as a regular galaxy.Answer and Explanation: A dwarf galaxy, as the name implies, is a small galaxy, ...

Surprisingly, the Sun is classed as aDwarf Stareven though it's bigger than 70% of stars in the galaxy. Dwarf Stars usually refer to averaged, normal main sequence stars, like our Sun. A White Dwarf is the result of a death of a small star that wasn't big enough to gosupernova. ...
What is the shape of the Magellanic Clouds? What gave the galaxy its distorted shape according to the Hubble Telescope? How big is a spiral galaxy? What type of star is Deneb? What are elliptical galaxies made of? What are dwarf galaxies?

One thing that isn't argued, however, is the number of moons around Pluto. Pluto has five known moons, most of which were discovered when New Horizons was in development or en route to the dwarf planet. A lot of asteroids have moons, too. These small worlds sometimes fly close to the...
Difference between Planet and Dwarf Planet 行星与矮行星之间的区别 For a planet to be fully recognised as a planet, it had to pass all the following rules. If it breaks any of those rules then it is a Dwarf Planet. If it is not spherical then it is classed as an Sun orbiting asteroid...
