Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...
Orrery. A small orrery showing Earth and the inner planets. An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often ...
For example, the model of Jupiter was located in the cavernous South Station waiting area. The properly-scaled, basket-ball-sized model is 1.3 miles (2.14 km) from the model Sun which is located at the museum, graphically illustrating the immense empty space in the Solar System. The objects in such large models do not move.
720,000 km/h (450,000 mi/h) [ 10] Orbital period. ~230 million years [ 10] The Solar System[ d] is the gravitationally bound system of the Sun and the objects that orbit it. [ 11] It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
Image title: Comparison of angular diameter of the Sun, Moon and planets with the International Space Station and human visual acuity, compiled by CMG Lee. To get a true representation of the sizes, view the image at a distance of 103 [1 / tan(33.5/60 * pi/180)] times the width of the largest (Moon: max.) circle.

NASA just announced that they've found 219 potential planets, and of those, 10 are close to the size of Earth and could possibly sustain life.
All planets orbit the Sun in elliptical orbits (image on the left) and not perfectly circular orbits. [71] The radius vector joining the planet and the Sun has an equal area in equal periods. [72] The square of the period of the planet (one revolution around the Sun) is proportional to the cube of the average distance from the Sun. [73]
