What might happen to life on Earth if the sun was smaller justify your answer?

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.

What would happen if the sun got bigger?

It will get so big, that it will eat Mercury, Venus and even Earth. When the sun is a red giant, it will be big and puffy, and start to blow off its outer layers out of the solar system. It will get smaller and smaller, eventually becoming what we then call a white dwarf.

What would happen to Earth if the sun were bigger?

If our world was as big as the Sun, then, like the water, our soil would have to be spread out to cover a much larger space. Less soil would mean less food, while the demand for food would stay the same.

What would happen if the Sun got bigger?

What would happen if the sun suddenly lost mass?

Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass (gasp, shudder, the horror!) then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.

What happens when the sun becomes small?

When the sun becomes small due to the nuclear reactions inside it , the pressure at the core will either increase the fusion rate because the mass has not decreased as much as the space it occupies decreases accelerating the fusion rate. What would happen if the Earth was bigger than the Sun?

What would happen if the Sun shrank smaller than Earth?

If for any reason the Sun shrank smaller than the Earth, this shrunken Sun wouldn’t have the mass to create fusion and would burn out completely. Our solar system would lose its only star. Since the Sun is the source of gravity that keeps us in orbit, all planets, the Earth included, would float away into space in search of another anchor.

What would happen if the Earth was next to the Sun?

The bad news is, the Earth would be uninhabitable, and the Sun… well, this massive star may no longer be a star. In the universe, size matters. And so does distance. It just so happens that the Earth is close enough to the Sun that it doesn’t freeze over like Mars. It’s also far enough away that it doesn’t get scorched like Venus.

What would happen if the volume of the solar system decreased?

Depending on the decreased amount, the planets might escape as well. Fusion would occur slower, lengthening the life of the Sun. If the volume decreased, gravity wouldn’t, because the mass stays constant. The density (amount of mass in a given volume) would increase, though.
