One million years, in astronomical terms is a short period of time. Models of star development dates our solar system at around 5 billion years; this ties in with radioactive dating of meteorites and moon rock samples which dates them at 4.5 billion years.
They're thought to be relatively young (by comparison to the planet itself), not more than about 600 million years old.
No. Betelgeuse is about 10 million years old, which is very young in terms stellar age and is barely enough time for a planet to form. Any planet so young would still be red hot from its formation. Despite being a young star, Betelgeuse is already dying as it has burned through the hydrogen in its core very quickly and has expanded into a red supergiant much brighter than it previously was. If a planet near Betelgeuse was the right temperature for life before the expansion, it would be too hot now.
Capella is estimated to be around 500 million to 700 million years old, which is relatively young compared to other stars in the universe.
A young planet is a planet that has recently formed and is still in the early stages of its development. These planets are typically hot, with high levels of volcanic activity and a lack of a stable atmosphere or surface features.
no way, not in a million years. haha
Yes.
It depends on your definition of "young" and "elder". 28% of the Mexican population has 14 years or less (32.1 million) while only 6.6% are 65 years old or older (7.5 million)
Mount Everest is approx 60 million years old
It all depends on what you consider young. Scientists estimate that the Earth is 4.5 billion years old which seems like a very long time to have existed. But, considering that our planet will probably continue to exist for another 7.5 billion years until the sun reaches Red Giant stage and engulfs us, the Earth still has a long way to go.
Yes, he is still in his teen years.
No, it is 8 million years old. That is nowhere near as old as the sun,(4.5 billion years), but it is not that young.
Compared to the sun, yes. It is only around 8 million years old.
