neptune is really big
The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.
They are all different sizes.
The planets in the solar system are in well-spaced out, stable, roughly circular orbits - they don't come close enough to collide with each other. Asteroids and comets, however, are on more elliptical, unstable orbits that often cross the orbits of the planets, and sometimes planets collide with asteroids and comets.
The Kepler Mission is a NASA space telescope designed to discover Earth-like planets orbiting other stars. Using a space photometer developed by NASA, it will observe the brightness of over 100,000 stars over 3.5 years to detect periodic transits of a star by its planets (the transit method of detecting planets) as it orbits our Sun. The mission is named in honor of German astronomer Johannes Kepler.
No but the sizes of OTHER planets and planetesimals can and do.
The inner planets are smaller than the gas giant (outer) planets.
inner planets are small and outer planets are big and cold and gas giants.
inner planets are small and outer planets are big and cold and gas giants.
Yes. Planets and moons come in all sizes and colors.
The sizes of inner planets are generally smaller compared to the sizes of the gas giants. The inner planets are Mercury, Venus, Earth and Mars. The gas giants are Jupiter, Saturn, Uranus and Neptune.

No, they are the size of uranus ;)
The sizes of the Sun and planets determine the strength of gravitational pull of the planets on each other and the Sun. The Sun's mass is so great that the planets can't escape from the Sun's pull and so as the planets are moving by the Sun pulls them back into orbit.
The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.
