It's interesting to see how the mass of something determines its nature. For example, an electron is 10⁻²⁹ grams. At this scale, the electron exists as a wave and a particle. Atoms are 10⁻²⁸ grams. Molecules are 10⁻²⁴ grams. The smallest grains of sand are 10⁻¹⁴ grams.

From 10⁻¹⁴ all the way to 10²⁰ kilograms are all the objects that we see in space, the asteroids and the planets. Earth is 10¹⁹, 10²⁰ kilograms. Up to the size of 2 times the mass of Earth, you'll see solid planets. Above that, they are gas giants like Neptune and Saturn, which are 10²⁷ kilograms.

Above that, heavier than Neptune and Saturn, is Jupiter, 10²⁸ kilograms. Jupiter is just a failed star. Anything higher than Jupiter will become a star. Fusion will start. Above 10²⁸ are stars where fusion happens.

You see, the mass determines its nature. It's pretty interesting.
