What is the scientific definition of Earth's distance from the Sun?

It is defined as the astronomical unit (AU), which equals exactly 149,597,870,700 meters, representing the average distance between Earth and the Sun centers.

Why convert Earth's distance from the Sun to millimeters?

Converting to millimeters allows relating vast celestial distances to very precise small-scale measurements used in science and engineering.

Can the Earth-Sun distance vary?

Yes, it changes slightly due to Earth's elliptical orbit, meaning exact conversions may vary depending on the astronomical unit value used.

Key Features

Converts Earth's distance from the Sun to millimeters using the exact IAU definition.
Supports expression of extremely large distances with high precision.
Browser-based and easy to use for astronomy, astrophysics, and engineering purposes.

Examples

0.5 Earth's distance from the Sun equals 74,800,000,000,000 mm.
2 Earth's distance from the Sun equals 299,200,000,000,000 mm.

Common Use Cases

Expressing distances within the solar system for astronomical studies.
Planning spacecraft routes and transfer orbits using precise distance units.
Converting scale measurements in educational and scientific materials.

Tips & Best Practices

Understand that astronomical distances expressed in millimeters result in very large values.
Use this conversion mainly for bridging astronomical scales with precise engineering measurements.
Remember the Earth-Sun distance varies slightly due to orbital eccentricity, so use the defined standard value for accuracy.

Limitations

Millimeter values become extremely large and impractical for everyday use due to the vast scale of the astronomical unit.
Exact conversion depends on the specific astronomical unit value because Earth's orbit varies between perihelion and aphelion.
