2. Jupiter vs. Earth: A David and Goliath Scenario
When contemplating how large is Jupiter compared to other planets, the most striking comparison is with Earth. Earth, our home, seems vast and expansive to us, but when placed next to Jupiter, it’s dwarfed significantly.
2.1 Diameter Comparison
Jupiter’s equatorial diameter is approximately 142,984 kilometers (88,846 miles), while Earth’s is a mere 12,742 kilometers (7,918 miles). This means Jupiter is roughly 11 times wider than Earth. Imagine lining up eleven Earths side by side – that’s approximately the width of Jupiter!
2.2 Volume Comparison
The difference in volume is even more astonishing. It would take about 1,321 Earths to fill up Jupiter. Think of Jupiter as a giant balloon; you could squeeze over a thousand Earths inside!
2.3 Mass Comparison
Jupiter’s mass is about 318 times that of Earth. This immense mass gives Jupiter its gravitational dominance in the solar system, influencing the orbits of asteroids and even affecting the movements of other planets.

3. How Large is Jupiter Compared to Other Gas Giants?
While Jupiter is the largest planet in the solar system, it’s helpful to see how it stacks up against its fellow gas giants: Saturn, Uranus, and Neptune.
3.1 Jupiter vs. Saturn
Saturn, famous for its stunning ring system, is the second-largest planet. Its equatorial diameter is about 120,536 kilometers (74,898 miles), which is roughly 84% of Jupiter’s diameter. While still massive, Saturn is noticeably smaller than Jupiter.
3.2 Jupiter vs. Uranus
Uranus, an ice giant with a unique sideways rotation, has an equatorial diameter of about 51,118 kilometers (31,763 miles). This makes Uranus about 36% of Jupiter’s size, a significant difference.
3.3 Jupiter vs. Neptune
Neptune, another ice giant, is slightly smaller than Uranus, with an equatorial diameter of about 49,528 kilometers (30,775 miles). Neptune is approximately 35% of Jupiter’s size.
Here’s a table summarizing the comparison:
| Planet | Equatorial Diameter (km) | Diameter Relative to Jupiter |
|---|---|---|
| Jupiter | 142,984 | 100% |
| Saturn | 120,536 | 84% |
| Uranus | 51,118 | 36% |

This table clearly illustrates Jupiter’s commanding size advantage over the other gas giants.
4. Jupiter vs. Terrestrial Planets: A Stark Contrast
The terrestrial planets – Mercury, Venus, Earth, and Mars – are rocky and much smaller than the gas giants. Comparing Jupiter to these planets highlights the vast differences in scale within our solar system.
4.1 Jupiter vs. Mercury
Mercury, the smallest planet in our solar system, has an equatorial diameter of only 4,879 kilometers (3,032 miles). Jupiter is almost 30 times wider than Mercury!
4.2 Jupiter vs. Venus
Venus, often called Earth’s “sister planet,” has an equatorial diameter of 12,104 kilometers (7,521 miles). Jupiter is nearly 12 times wider than Venus.
4.3 Jupiter vs. Mars
Mars, the “Red Planet,” has an equatorial diameter of 6,779 kilometers (4,212 miles). Jupiter is more than 21 times wider than Mars.
Here’s a summary table:
| Planet | Equatorial Diameter (km) | Diameter Relative to Jupiter |
|---|---|---|
| Jupiter | 142,984 | 100% |
| Mercury | 4,879 | 3.4% |
| Venus | 12,104 | 8.5% |
