Detailed explanation-1: -All plants would die and, eventually, all animals that rely on plants for food-including humans-would die, too. While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.
Detailed explanation-2: -Without the Sun, Earth’s land, water, and air would all be frozen solid! Life on Earth would cease to exist. That’s because almost all living things rely on the steady light and heat of the Sun. The Sun’s heat makes liquid water on our planet possible.
Detailed explanation-3: -0-30 seconds in the vacuum of space, less than 2 minutes on Mercury, less than a second on Venus, 80 years on Earth, 3 minutes on the Moon, 2 minutes on Mars, less than a second on Jupiter, and less than a second on Saturn, Uranus, and Neptune.
Detailed explanation-4: -The answer is that the sun is the ultimate source of heat in our solar system, so if you are not in sunlight, and there is no air or ground (or portable heater) to carry sunlight’s energy to you, then you have no source of heat. Cold is simply the absence of heat.
