Diameter of planets and their distance from the Sun in kilometers (km):
The best way to appreciate the size of our solar system is by creating a scaled model of it that shows how far from the sun the eight planets are located. Astronomers use the distance between Earth and sun, which is 93 million miles, as a new unit of measure called the Astronomical Unit.
Distances in the Solar System are huge. Too huge for kilometres or miles to be useful. Instead, we use astronomical unit (AU). One AU is the distance from the Earth to the Sun. It is equal to 150 million kilometres. Solar System Formation. The Solar System formed from a huge cloud of gas and dust, which collapsed around 4.6 billion years ago.
The boundary in the Solar System beyond which those volatile substances could coalesce is known as the frost line, and it lies at roughly five times the Earth's distance from the Sun. [5] Orbits Animations of the Solar System's inner planets orbiting.
See how the sizes of planets and the distances between them compare. And find out why it's so hard to create a scale model of the solar system that accurately represents both size and distance on a single screen or the page of a book. ... the planets’ positions are constantly changing as they revolve around the Sun.

Our solar system's largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun. That's 5.2 AU. Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale.
One astronomical unit (or AU) is the distance from the Sun to Earth, or about 93 million miles (150 million kilometers). The Oort Cloud is the boundary of the Sun's gravitational influence, where orbiting objects can turn around and return closer to our Sun. The Sun's heliosphere doesn't extend quite as far.
This 2D visual model illustrates the scale of the sun and planets in our solar system, and their current distance from each other.

One AU is the distance from the Sun to Earth's orbit, which is about 93 million miles (150 million kilometers). When measured in astronomical units, the 886,000,000-mile (1,400,000,000-kilometer) distance from the Sun to Saturn's orbit, is a much more manageable 9.5 AU.
