The Solar System

Distances in the solar system are commonly measured in Astronomical Units (AU). An AU is simply the average distance between the Earth and the Sun. Because the Earth''s orbit around the Sun is an ellipse, the Earth is not always the same distance from the

Astronomers sometimes divide the Solar System structure into separate regions. The inner Solar System includes Mercury, Venus, Earth, Mars, and the bodies in the asteroid belt. The outer Solar System includes Jupiter, Saturn, Uranus, Neptune, and the bodies in the Kuiper belt. Since the discovery of the Kuiper belt, the outermost parts of the Solar System are considered a distinct r

Cosmic Distances

For much greater distances — interstellar distances — astronomers use light years. A light year is the distance a photon of light travels in one year, which is about 6 trillion miles (9 trillion kilometers, or 63,000 AU). Put another way, a light year is how far you''d

Astronomical Unit (AU)

Since 1 AU is approximately equal to 150 million kilometers, astronomers often use this conversion to calculate distances in the solar system. Another common conversion is between AU and light-years, with 1 AU being equal to about 0.0000158 light-years.

Data Table for Planets & Dwarf Planets: AU, Inclination,

*Negative values of rotation period indicate that the planet rotates in the direction opposite to that in which it orbits the Sun. This is called retrograde rotation. The semimajor axis (the average distance to the Sun) is given in

19.1 Fundamental Units of Distance

From the various (related) solar system distances, astronomers selected the average distance from Earth to the Sun as our standard "measuring stick" within the solar system. When Earth and the Sun are closest, they are about 147.1 million kilometers apart; when Earth and the Sun are farthest, they are about 152.1 million kilometers apart.

Model the Distances between Planets in our Solar System

You will make a model of the solar system. Imagine you shrink the solar system so much that the distance from Earth to the Sun becomes 10 cm. When you shrink the solar system this much, all the planets shrink in size, so they become too small to see. You

The Solar System

To measure distances in the solar system, astronomers frequently use the astronomical unit (AU), which is the average distance from the center of the Earth to the center of the Sun. One AU is equal to 149,597,871 kilometers or 92,955,807 miles.

Astronomical unit (AU, or au) | Definition, Conversion, & Facts

Astronomical unit, a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles). The astronomical unit provides a convenient way to express and relate distances of objects in the solar system and to carry out astronomical calculations.

Astronomical unit

With the definitions used before 2012, the astronomical unit was dependent on the heliocentric gravitational constant, that is the product of the gravitational constant, G, and the solar mass, M .Neither G nor M can be measured to high accuracy separately, but the value of their product is known very precisely from observing the relative positions of planets (Kepler''s third law
