Chandra :: Resources :: Milky Way GalaxyEverything has a shadow! Shadows illustrate how three-dimensional objects can be viewed in two dimensions. Students explore the Earth and Sun's postions in relation to the constellations of the ecliptic with a small model. They explore the motions of the Earth and inner planets in a larger classroom-size model. A very interactive and fun activity. Does the Moon always look the same?

All rights reserved. The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids. Astronomers believe it formed about 4. Along with the sun, our cosmic neighborhood includes the eight major planets. The closest to the sun is Mercury , followed by Venus , Earth, and Mars.

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. The four outer planets are giant planets , being substantially more massive than the terrestrials.
