Celestial Window observatory construction. Size of the stars No one knows exactly how big the stars are but by using a variety of methods, astronomers have been able to roughly calculate the diameters of many nearby stars. If the earth were shrunk to 1 inch in diameter it would be the size of a quarter. Other celestial objects appear below for comparison after having been scaled down by the same amount. Stars appear to be tiny twinkling flickers of light in the sky that seem almost to be snuffed out by an occasional breeze on a summer night, but they are most definitely larger than what they appear.

Fill in the diameter of the Sun you want your model to be scaled by. You can fill in either the red bordered inches box or the green bordered millimeters box. Important: Only fill in one box. If both are filled in you will get a dialog box asking you to clear one of the boxes. Use the Clear button to clear the entire form.

The Solar System [a] is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun indirectly—the moons —two are larger than the smallest planet, Mercury. The Solar System formed 4. The vast majority of the system's mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus , Earth and Mars , are terrestrial planets , being primarily composed of rock and metal.

From the ringed beauty of Saturn, to the massive hulk of Jupiter, to the lead-melting temperatures on Venus, each planet in our solar system is unique — with its own environment and own story to tell about the history of our Solar System. What also is amazing is the sheer size difference of planets. While humans think of Earth as a large planet, in reality it is dwarfed by the massive gas giants lurking at the outer edges of our Solar System. This article explores the planets in order of size, with a bit of context as to how they got that way. No human was around 4. As more information comes in, some of our theories of the Solar System must change to suit the new evidence. Today, scientists believe the Solar System began with a spinning gas and dust cloud.

This lists the logos of programs or partners of NG Education which have provided or contributed the content on this page. Review planet order and relative sizes in our solar system. Ask students to point out the location of Earth. Then challenge them to identify all of the planets, outward from the sun left to right : inner planets Mercury, Venus, Earth, Mars; outer planets Jupiter, Saturn, Uranus, Neptune, and Pluto. Remind students that Pluto is no longer considered a planet in our solar system; it was downgraded to the status of dwarf planet in Point out the locations of the asteroid belt between Mars and Jupiter and Kuiper belt past Pluto if they were included in this illustration.
