Size comparison planets solar system

How do I compare the sizes of our planets?

A simple way to compare the sizes of our solar system's planets, the sun and the moon. You can compare them side by side or with the smaller object positioned on the surface of the larger one. Get better texture maps of the surface - especially Pluto!

What are the smallest and largest planets in order?

The size of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter. The size of planets in our solar system varies dramatically. Let’s explore the sizes of the planets, including their radius and diameter in both kilometers and miles, and their relative sizes compared to Earth.

What are the approximate sizes of the planets relative to each other?

This illustration shows the approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, followed by the dwarf planet Pluto. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's.

How many planets are in our Solar System?

According to NASA, this is the estimated radii of the eight planets in our solar system, in order of size. We also have included the radii sizes relative to Earth to help you picture them better. Eight planets and a dwarf planet in our Solar System, approximately to scale. Pluto is a dwarf planet at far right. At far left is the Sun.

What are the sizes of planets based on the equatorial diameter?

This is a simple guide to the sizes of planets based on the equatorial diameter – or width – at the equator of each planet. Each planet’s width is compared to Earth’s equatorial diameter, which is about 7,926 miles (12,756 kilometers). At the bottom of the page, there is a handy list of the order of the planets moving away from our Sun.

How wide is a planet compared to the Earth's equatorial diameter?

Each planet’s width is compared to Earth’s equatorial diameter, which is about 7,926 miles (12,756 kilometers). At the bottom of the page, there is a handy list of the order of the planets moving away from our Sun. Jupiter is the largest planet in the solar system.
