Planet Size Comparison (720p)

If you’re interested in planets, the good news is there’s plenty of variety to choose from in our own Solar System. From the ringed beauty of Saturn, to the massive hulk of Jupiter, to the lead-melting temperatures on Venus, each planet in our solar system is unique — with its own environment and own story to tell about the history of our Solar System. What also is amazing is the sheer size difference of planets. While humans think of Earth as a large planet, in reality it is dwarfed by the massive gas giants lurking at the outer edges of our Solar System. This article explores the planets in order of size, with a bit of context as to how they got that way. Size of the eight planets 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. Jupiter (69,911 km / 43,441 miles) – 1,120% the size of Earth Saturn (58,232 km / 36,184 miles) – 945% the size of Earth Uranus (25,362 km / 15,759 miles) – 400% the size of Earth Neptune (24,622 km / 15,299 miles) – 388% the size of Earth Earth (6,371 km / 3,959 miles) Venus (6,052 km / 3,761 miles) – 95% the size of Earth Mars (3,390 km / 2,460 miles) – 53% the size of Earth Mercury (2,440 km / 1,516 miles) – 38% the size of Earth
