There are different types of "red stars". Red giants are often relatively young. Red dwarves, on the other hand, may be very old. However, some of them may also have formed recently.
The coolest stars are red in color. They are classified as red dwarfs and have surface temperatures ranging from about 2,500 to 3,500 degrees Celsius.
The sun is hotter than red stars but cooler than blue stars,
A stars color is determined mainly by it's surface temperature. They tend to range from Blue (hottest) thru white and yellow to red (coolest). One thing to bear in mind tho is that a Red Giant star, for example, produces more heat than a smaller yellow star but because the star is much bigger the heat is more spread out (because the surface area is so much bigger) and therefore it appears red.
Red stars are the coolest of the stars.However, for completeness:A brown dwarf is cooler.A white dwarf can be the hottest and one of the coolest (Depending on age)A black dwarf is the coldest.
The largest stars, known as red hypergiants, can appear red or orange in color due to their cool surface temperatures. The smallest stars, like red dwarfs, are cooler and emit a dim red light.
No. Unless a star is a red giant (in which case it is old and dying) a red color does not indicate anything about its age.
It is the red star hope this helps,Jazz
Young stars are blue because they are also hotter than older stars, which have cooled down to make white, yellows, then oranges, then red.
No. While blue stars generally do not last as long as others, it is possible to find relatively young yellow or red stars.
No. A star's color does not necessarily say anything about its age. A red giant or red supergiant is a star entering its final stages, but how old it is depends on its mass. More massive stars die sooner. Red dwarfs are stars that simply have a low mass and can be any age.
No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.
The youngest stars are protostars which are still forming within giant molecular clouds. The oldest stars in the universe are believed to be Population II stars, which are remnants from the early universe and can be found in globular clusters.
The youngest nude Disney channel star is Miley Cyrus :)
Only the youngest one, Cissy, I believe, is still alive.
Most new, young, stars can be found in the arms of spiral galaxies
Evan Lysacek is the youngest, born on June 4, 1985.
Red stars are cooler than blue stars
