Size and Distance
With a radius of 2,106 miles (3,390 kilometers), Mars is about half the size of Earth. If Earth were the size of a nickel, Mars would be about as big as a raspberry. From an average distance of 142 million miles (228 million kilometers), Mars is 1.5 astronomical units away from the Sun.
Saturn is the second largest of the gas giants; with a mean diameter of 120,536 km, it is just slightly smaller than Jupiter. … Still, this makes Saturn the second most-massive planet in the Solar System, with 95 times the mass of Earth.
Pluto is now classified as a dwarf planet because, while it is large enough to have become spherical, it is not big enough to exert its orbital dominance and clear the neighborhood surrounding its orbit.
Uranus is slightly larger in diameter than its neighbor Neptune, yet smaller in mass.
Problem 8 – The Dwarf Planet Pluto is 1/3 the size of Mars. How large is Jupiter compared to Pluto? Answer: Jupiter = 1/11 Earth, Mars= 1/2 Earth, so Pluto= 1/3 x 1/2 = 1/6 Earth, and 1/66 Jupiter.
“Mars is believed to be geologically older than Earth, yet [both] formed out of the same material very close to each other,” Matthew Clement, the paper’s lead author and a graduate researcher in planetary science at the University of Oklahoma, told me.
Uranus was formed at the same time as the rest of the Solar System, from a large spinning disk of gas and dust. Astronomers think that all this happened about 4.6 billion years ago! So Uranus is about 4.6 billion years old.
Uranus is an ice giant. Most of its mass is a hot, dense fluid of “icy” materials – water, methane and ammonia – above a small rocky core.Aug 4, 2021
Option 2: A Table
6.4 Earth days
On approach in July 2015, the cameras on NASA’s New Horizons spacecraft captured Pluto rotating over the course of a full “Pluto day.” The best available images of each side of Pluto taken during approach have been combined to create this view of a full rotation. Pluto’s day is 6.4 Earth days long.Nov 20, 2015
The five best-known dwarf planets are Ceres, Pluto, Makemake, Haumea, and Eris. Except for Ceres, which lies in the main asteroid belt, these small worlds are located in the Kuiper Belt. They’re considered dwarfs because they are massive, round, and orbit the Sun, but haven’t cleared their orbital path.
Perhaps surprisingly, Mars is only 30% wider than Mercury’s diameter of 3,032 miles or 4,880 km.

Saturn is very large and is the second largest planet in the Solar System. However, it is made up mostly of gas and is less dense than water. Since it is lighter than water, it can float on water. None of the other planets in our Solar System can do this because they have a higher density than water.
Mercury is much smaller than Venus, Mercury is about twice as close to the Sun as Venus, … Mercury has no atmosphere, while Venus has a very thick atmosphere.
The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets’ formation.
