## Does the sun have a smaller mass than Earth?

The mass of the sun is 1.989 x 1030 kilograms, about 333,000 times the mass of the Earth.

## How big is the sun compared to Earth?

It holds 99.8 percent of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.

## Which planets have less mass than Earth?

What is the mass of the other planets in our solar system?

Planets (in order of least massive to most massive) Mass (in kilograms) Each planet’s mass relative to Earth
Earth 5.97 x 1024 1
Uranus 8.68 x 1025 14.5
Neptune 1.02 x 1026 17.1
Saturn 5.68 x 1026 95.2

## Are you lighter in space?

Since the gravitational force depends on your mass, the Earth’s mass and the distance between those, it doesn’t change. Again, the magnitude of the gravitational force doesn’t change. The only thing that can happen is for the floor to push less. From this, you feel lighter./span>

## Does your weight change in space?

While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change. They still take up just as much space as they do here on Earth. This is the important difference between mass and weight.

## Why does your weight change in space but not your Mass?

Mass does not change whether it is measured on Earth or the ISS. Weight can change depending upon the gravitational pull such as on the Moon where weight is reduced to one-sixth that of on Earth.

## Are there bodies in space?

Bodies, no. But ashes of quite a few people have been launched into space. (The Challenger astronauts never actually got into space.) Three Russian cosmonauts died during the descent when a valve let all the air out of their spacecraft.
