It is possible that there could be planets where terrestrial-type life could survive orbiting a neutron star, but they are likely extremely rare and transient. The habitable zone where liquid water can persist around a star has a range ≈ 0.7 L ∗ to 1.4 L ∗ AU, where L ∗ is the luminosity of the star measured in solar luminosities.
WebIt is not true that planets cannot exist without their sun. There are thought to be many planets cruising around the galaxy that have no sun. They are called rogue planets, and by some counts there are more of them than there are stars. By a freak accident, like another star crossing it’s path, the Earth could be thrown out of the solar system. WebUnfortunately, the answer is yes. The sun, after all, is a star, and all stars will explode in due time, but fortunately, this won’t happen anytime soon, and definitely not in our lifetime. According to scientists, our Sun will only explode when it runs out of fuel in around 5 billion years, so it’s still a very very long time in the future.
