How Far Is the Moon from Earth?
The average distance from Earth to the Moon is approximately 384,400 kilometers (238,855 miles). This gap may seem small in cosmic terms, but it’s still vast enough to inspire one of astronomy’s most fascinating questions: can all planets fit between Earth and Moon?
Total Diameters of the Planets
To determine whether all planets fit between Earth and Moon, we need to look at their diameters. Here are the average diameters of the planets in kilometers:
- Mercury: 4,880
- Venus: 12,104
- Mars: 6,779
- Jupiter: 139,820
- Saturn: 116,460
- Uranus: 50,724
- Neptune: 49,244
Add those up and you get approximately 380,011 kilometers. That’s just under the average Earth–Moon distance. So technically, can all planets fit between Earth and Moon? Yes—just barely.
Do They All Fit Between Earth and Moon?
Yes, they do! If you lined up all the planets—excluding Pluto, which is now classified as a dwarf planet—their total width is slightly less than the distance from Earth to the Moon.
This supports the viral claim and answers the question: can all planets fit between Earth and Moon? Absolutely, at least when talking about straight-line diameters.
Real Visualizations & Examples
Astronomy educator James O’Donoghue created an animation showing the planets stacked side by side between Earth and the Moon. It perfectly demonstrates that yes, can all planets fit between Earth and Moon is more than a meme—it’s a scientific curiosity supported by real math.

Try visualizing Earth on one side, the Moon on the other, and the gas giants squeezed in between. It’s not only fun—it’s educational.
Conclusion
So, can all planets fit between Earth and Moon? Based on actual planetary diameters and the average lunar distance, yes, they can. This fun fact offers a sense of scale for just how enormous our solar system really is—even when something is “close” like the Moon.

Frequently Asked Questions
Do the planets touch each other in this fit?
No. If stacked perfectly, there would be minimal space between them, but no overlap.
Does this include Pluto?
No. Pluto is a dwarf planet and not included in the primary 8-planet calculation.
Why does this comparison matter?
It helps people understand the vastness of space and the relative sizes of celestial bodies.
Who first discovered this fact?
The concept gained popularity through educational animations and astronomy forums, notably by James O’Donoghue.
