How long does a star usually live?
110827
Considering that the vast majority of stars in the universe are small M type stars I would say that the average life span is 1 trillion years (M type stars can live for 3 trillion years)... The sun is a G2 V type star and will not live that long. It has a few billion years left on the main sequence. After that it will begin to expand and turn into a red giant. After another billion years or so its outer layers will just fizzle out into space leaving a white dwarf. So the total life span of the sun is about 10 billion years.

Some can live up to a month, but some only live a matter of hours or days.

The sun is a star and so it will have its time when it will die, so I believe that if something can die then it must be alive.

After a star dies, there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow, even though it is not producing any energy. Eventually, the star cools off and does indeed simply become a hunk of ash, which we call a "black dwarf." \n\npeace

The average lifespan for a wolf in the wild is only 9 years. Wolves in captivity live much longer. They reach sexual maturity at about 2 years of age and have finished growing.

Greetings,\n\nI would imagine they both could be depending on the size, age, and life cycle of the particular star.\n\n-matt

Gerbils usually live 3-4 years. Have a nice week. :)

This is a very difficult question. We don't really know how many stars currently exist, so let's rephrase the question to "how many stars in the night sky visible to the naked eye still exist?" (An easier question would be "does star xyz still exist?") If all of these stars are classified into groups whose average lifespans are known, and if the current ages of these stars can be estimated, then using the estimated time that light takes to travel from a particular star to Earth, we can determine if the star has already gone supernova, or if it has darkened. Since most stars visible to the naked eye are relatively young (as compared with super-distant stars visible through huge telescopes), it is likely that a significant proportion of them do still exist. But, again, the question is extremely difficult, but makes for some good thinking.

The people who said it is closer to 4.5 to 5 *billion* years, are correct.\n\nThe sun is a class G star, which has a lifespan of about 10 billion years (the main part of it's lifespan ... after 10 billion years, it expands and goes through a second, larger but shorter-lived phase).  The sun is about 4.5  to 5 billion years old, which means that it's about halfway through its main lifespan.   So it will be here a little bit more than it has been here already ... which is a *very* long time.\n\nIf the earth hasn't been physically destroyed by an asteroid, or some man-made catastrophe we cannot imagine yet, I am quite sure that life will still be going strong on the earth at that time .. but that humans will be long gone.   Either we will have left after making the planet uninhabitable for ourselves, or we will have killed each other off, or we will go extinct through natural causes (like an asteroid that doesn't destroy the planet, but does wipe out most life).  But in all cases, some life forms will survive, and will do quite fine without us.\n\nEven if we blew each other to pieces with nuclear weapons, and wiped out almost all life on the planet due to radiation, some life would survive the radiation (e.g. in the deep oceans) and life would eventually bounce back ... and would begin the process of evolution all over again.  That's what life does.

Japan has the longest healthy life expectancy of 74.5 years. Austria follows by 73.2 years, and France 73.1 years.

Our sun is indeed a star. As a star,it will go through all the phases that other stars go through like BIG BANG and etc. Yes,our sun will explode one day and that day will be in another million or billion years of time. So,don't worry about it now. Worry about your great grandchildren. Anyway i hope that i had answered your question. Take care.

We have one birthday- each year of our lives we Celebrate that day- to honor our life and birth in years-\n\nThe AVERAGE life expectancy in the USA is 77 yrs- of course some have much shorter lives, and some have much longer.

Life expectancy of animals and plants\nThe vast majority of animals have shorter life expectancies than humans do, and typically the lifespan of the animal increases with size. Some examples include:\n\nCats have lifespans in the 14-20 year range. \nLarge herbivores (cattle, horses, camels, deer) in the 30-50 year range. \nBirds usually live 10-30 years, with parrots - particularly macaws - and several seabirds notable exceptions, with lifespans ranging from 40-80 years. \nElephants have lifespans of 50-80 years. \nBlue whales can live from 40 to 80 years. \nBowhead whales are thought to live up to 200 years, with a few individuals found to have century-old harpoons embedded in their blubber. \nDogs live 10-25 years. \nSome turtles live to 150 years or more. \nCertain trees have almost outlived recorded human history; the baobab tree can live for 1,000-4,000 years, although it is understandably difficult to measure this. Similarly long-lived are olive trees, domesticated in the Mediterranean. Several olive trees still alive today were nurtured by the ancient Greeks. \nMany corals can potentially live for over 100,000 years. However, there is no consensus among marine biologists how to determine age of a coral, and whether or not it is really a single organism.

I think answer number 1 is correct. However, it probably depends on the individual. Some people wouldn't last more than 24 to 36 hours.

main sequence stars are at their most stable, during their main sequence lifetime when they are just burning hydrgen\n\nhope this is as specific as you need.

It depends on the species. Large apple snails can live over 10 years. Small pond, ramshorn, trumpet, etc. snails may live 3-6 years but most die before that when they are eaten or due to poor water quality or something else. Trapdoor snails may live 5-10 years. The average run-of-the-mill small aquarium snail is lucky to live a few years with all the predators and dangers in the average tank. But, really there is no definitive answer to your question. I don't know that anyone's done real studies on this. It's just word of mouth as to how long someone's snail may have lived.

Well, smokers and drinkers usually have shorter life expectancy, but some smoke and drink all their lives and still live to a ripe old age.\n\nIt is hard to predict how long you will live depending on your current health.
