What are the 5 categories of a star?
The five categories of a star classification are O, B, A, F, G, K, and M. These categories are based on the star's surface temperature, color, and spectral features. O stars are the hottest and bluest, while M stars are the coolest and reddest.
What categories does your sun belong?
Our Sun belongs to the category of stars known as main sequence stars, specifically a G-type main sequence star. It is classified as a yellow dwarf star.
What are the names of the star colors?
The colors of stars are classified into categories such as red, orange, yellow, white, and blue, based on their surface temperature. The categorization is part of the spectral classification system used by astronomers to describe the characteristics of stars.
What are some characteristics used to classify stars?
In Astronomy stars can be classified by theircolor (temperature)composition (as found by their spectrum)agelocation in a galaxymassproximity to other stars
How are stars classified by size and temperature?
Stars are classified by size using the Hertzsprung-Russell diagram, which categorizes them based on luminosity and temperature. Stars are sorted into main sequence, giant, supergiant, or dwarf categories. Temperature determines a star's color, with hotter stars appearing blue-white and cooler stars appearing red.

What are the three main categories of dead stars?
The first category is the white dwarf these are the stars that our Sun will become. The second category are the more massive stars that will collapse down to neutron stars. The final category is a black hole.
What are the 5 categories of stars on the Hollywood walk of fame?

What categories does your sun belong?
Our Sun belongs to the category of stars known as main sequence stars, specifically a G-type main sequence star. It is classified as a yellow dwarf star.
How do clusters of O and B stars compare to clusters of T Tauri stars?
T Tauri stars are pre-Main Sequence stars which are large but not as hot as O and B Main Sequence stars. They mainly fall in the categories of F, G, K or M, and they are not yet on the Main Sequence because they are still accreting mass and are still very young and unstable.
What is the opposite of dwarf?
In astronomy, stars are divided mainly into two categories, "dwarfs" and "giants". There are some specialized categories ("bright giants", "hypergiants") but overall ... giants is a pretty good answer.(Even dwarf stars can still be pretty big, our own Sun, with about a million times the volume of Earth, is considered a dwarf.)

Can you name 5 different categories of celestial that make up our solar system?
Five I can name are: asteroids, planets, black holes, moons, and stars.
What are the five primary types of stars?
The five primary types of stars are the red dwarf star, yellow star, blue giant star, giant star, and super giant star. The billions of stars in the universe fall under one of these classifications.
What are the structures in space from smallest to largest?
From smallest to largest, the structures in space are: planets, stars, star clusters, galaxies, galaxy clusters, and superclusters. Within each of these categories, there is a wide range of sizes and variations.
