How big is the Solar System?
While some astronomers are content to claim that the size of the solar system is around 122 AU, others point out that the solar system should really be defined by the reach of its gravity. In other words, if an object can be said to orbit the Sun, then it should be considered part of the solar system.
How do astronomers measure the size of our Solar System?
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.
What is the largest planet in the Solar System?
Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale. It is an average distance of 484 million miles (778 million kilometers) from the Sun, which is 5.2 AU.
How big is the Sun?
On this scale, the Sun, by far the largest thing in our solar system, is only a ball about two-thirds of an inch (17 millimeters) in diameter sitting on the goal line — that's about the width of a U.S. dime coin.
How many planets are in the Solar System?
Our solar system consists of 4 inner planets ( Mercury, Venus, Earth and Mars ) and 4 giant planets (Jupiter, Saturn, Uranus and Neptune ). There are also several dwarf planets ( Pluto, Ceres and Eris are just a few ) around 200 moons, and millions of asteroids and comets.
How do students learn about the size of the Solar System?
In this activity students learn about the size of the Solar System, beginning with the Earth and Moon and reaching out to encompass the entire Solar System. Develop an understanding of the scale of the Solar System, starting from the closest object to the farthest. Use numeracy skills to calculate a scale distance model of the Solar System
