What are the three types of star systems?
Multiple-star systems are called triple, ternary, or trinary if they contain 3 stars; quadruple or quaternary if they contain 4 stars; quintuple or quintenary with 5 stars; sextuple or sextenary with 6 stars; septuple or septenary with 7 stars.

Types of Binary Stars
- Visual binaries.
- Spectroscopic binaries.

What are the types of binary system?
The most common binary systems are binary stars and binary asteroid, but brown dwarfs, planets, neutron stars, black holes and galaxies can also form binaries. A multiple system is like a binary system but consists of three or more objects such as for trinary stars and trinary asteroids.

How many main types of stars are there?
seven main types
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.
What 3 factors control the apparent brightness of a star?
Apparent magnitude is the brightness of a star when viewed from Earth. Three factors control the apparent brightness of a star as seen from Earth: how big it is, how hot it is, and how far away it is.

What type of stars are binary stars?
Binary classifications Binary stars are two stars orbiting a common center of mass. The brighter star is officially classified as the primary star, while the dimmer of the two is the secondary (classified as A and B respectively).

What are the 4 types of star classification?
Luminosity class 0 or Ia+ is used for hypergiants, class I for supergiants, class II for bright giants, class III for regular giants, class IV for subgiants, class V for main-sequence stars, class sd (or VI) for subdwarfs, and class D (or VII) for white dwarfs.
