Solar System Scale Model
Explore the solar system to scale. Toggle between true distance and true size modes.
What is a solar system visualizer?
This interactive tool provides a visual representation of our solar system, showing the relative positions, sizes, and orbits of the planets. It helps you understand the vast scale of our cosmic neighborhood — from Mercury orbiting close to the Sun to Neptune at the outer edge, 4.5 billion kilometers away.
Visualizing the solar system to scale is challenging because the distances are enormous compared to the sizes of the planets. If Earth were the size of a marble, Jupiter would be a soccer ball 550 meters away, and Neptune would be 4.4 kilometers away. This tool uses adjustable scales to show both orbital distances and relative planet sizes.
How to use this tool
Explore the interactive solar system model. Zoom in and out to see different scales. Click on individual planets to view their detailed information. The tool shows orbital distances, planet sizes, and key facts. Toggle between scale modes to compare distances versus sizes.
Solar system facts
- The Sun contains 99.86% of the total mass of the solar system.
- Light from the Sun takes about 8 minutes to reach Earth and over 4 hours to reach Neptune.
- The asteroid belt between Mars and Jupiter contains millions of rocky objects, but their total mass is less than 4% of the Moon's mass.
- Jupiter's gravity acts as a shield, deflecting many comets and asteroids that might otherwise hit Earth.
Frequently asked questions
How old is the solar system?
The solar system is approximately 4.6 billion years old. It formed from a giant cloud of gas and dust (a solar nebula) that collapsed under its own gravity. The Sun formed at the center, and the remaining material formed a disk that eventually coalesced into the planets, moons, asteroids, and comets we see today.
What is beyond our solar system?
Beyond Neptune lies the Kuiper Belt (home of Pluto and other dwarf planets), then the scattered disk, and finally the Oort Cloud — a hypothetical shell of icy objects extending up to 1.5 light-years from the Sun. Beyond that is interstellar space. The nearest star, Proxima Centauri, is 4.24 light-years away.
