what is the biggest object in our solar system, and how many earths could fit inside it?
The Sun dominates as the largest object in our solar system.
It dwarfs all planets and moons, holding over 99.8% of the system's total
mass.
Size Breakdown
The Sun's diameter stretches to about 1,392,000 km, roughly 109 times Earth's width.
Jupiter ranks second at 142,984 km across (11 times Earth's diameter), but no other body comes close.
Here's a quick size comparison table:
| Object | Average Diameter (km) | Ratio to Earth |
|---|---|---|
| Sun | 1,392,000 | 109.1 |
| Jupiter | 142,984 | 11.2 |
| Saturn | 120,536 | 9.4 |
| Earth | 12,756 | 1 |
Volume and Earths Inside
You could fit around 1.3 million Earths inside the Sun's volume.
This stems from its massive scale—its radius is so vast that the volume scales
cubically (over a million times Earth's).
For context, Jupiter holds about 1,300 Earths, highlighting why the Sun reigns supreme.
Fun Cosmic Perspective
Imagine stacking Earths like cosmic marbles: the Sun's fiery core could swallow our planet over a million times without bulging.
Recent NASA visuals (as of 2025) reinforce this, showing Jupiter's own Earth- packing limit at just 1,000—mere pocket change next to the Sun.
No trending debates shift this; it's settled astronomy amid 2026 solar observation buzz.
TL;DR: Sun is biggest; ~1.3M Earths fit inside.
