What is the life expectancy for alphs centauri b?

Alpha Centauri B is a star, not a planet, and it has a life expectancy of approximately 10 billion years. As a member of the Alpha Centauri star system, it is a bit older than our Sun, which has an estimated life expectancy of about 10 billion years as well. However, Alpha Centauri B is expected to have a stable lifespan, continuing to shine for several billion more years before eventually evolving into a red giant and then a white dwarf.


Which planet has the shortest year?

We're currently only aware of one planet that supports any life. That planet is Earth, the one you're presumably on right now. Since this is the only planet with life, it has both the longest and the shortest life span. Life span varies depending on what organism you're talking about. The human life span -- the longest a human is confirmed to have lived -- is approximately 122 years old. Life span is different than life expectancy. Life expectancy is the average length of a human life, and it varies widely based on factors such as geography, poverty, gender, race, etc. If you went to any other planet in our solar system without proper protective equipment (spacesuit, etc.), your life expectancy would be exceedingly small.


How many life years is from here from mars?

It takes about 7 months for a spacecraft to travel from Earth to Mars. The average life expectancy on Earth is around 70 years. So in terms of "life years," the trip to Mars would be equivalent to about 0.8% of an average person's total lifespan.


What is the life expectancy of solar landscape lights?

Solar landscape lights should last between 8-10 hours depending on the amount of sunlight they receive during the day. During the winter they may not receive enough sunlight through the daylight hours in order to last the night.


What would happen if an asteroid with diameter of 1-3 kilometer range smashed into earth?

If an asteroid with a diameter of 1-3 kilometers hit Earth, it could cause widespread devastation, with global effects. The impact would generate massive tsunamis, earthquakes, and fires, leading to significant loss of life and destruction of infrastructure. It could also potentially alter the climate and have long-term consequences on the environment.
