(well in pics) but it really wont happen because earth is like a big magnet but the gravitational pull will not let the other planets collide with the earth or (even the sun) some say !!
Planets around the sun in nearly circular orbit . The radii of these orbits differ widely
That applies to all planets. Planets go around the Sun in elipses - the Sun is at one of the focal point of the elipse. The focal point is not the center.
Astronomer's have not been able to count all the planets in the Andromeda Galaxy. The Andromeda Galaxy is home to one-trillion stars. The Andromeda Galaxy is expected to collide with the Milky Way in the next 4.5-billion years.
Not at the same time, no.
The star TRAPPIST-1 has three known planets. Such planets are not easy to utterly destroy, unless they happen to fall into their star, or collide with one another (in which case they would presumably form a larger planet).
All particles of all things are in constant motion. Particles in a liquid collide, but the rate is subdued by the viscosity of the liquid.
It would be a spectacular sight, but no one has ever observed it happening. I think if you apply the current definition of planet to the bodies involved, you could demonstrate that if two 'planets' collide then at least one of them is not a planet.
-They were all formed by the Big Bang (a star exploded, sending shockwaves through a cloud of dust which condensed and formed the solar system. the remaining particles started to collide with each other, getting bigger and bigger as their gravity increased.) -They all orbit around the sun. -All of the planets except for Mercury and Venus have at least one moon that orbits the planet. -All of the planets can clear "junk" out of its atmosphere (if their gravity is strong enough the "junk" will be pulled in and no longer remain in its atmosphere). This is also the difference between dwarf planets (3 of them are Pluto, Eris, and Ceres) and planets.
The auroa borealis occurs when all of the planets becomes the most gasiest and they all collide into one planet creating different colors within the sky because of the different textures of each planet. The aurora borealis rarely occurs and there havent been one present in centuries!!!!!
In the past some planets or protoplanets did collide with each other. Indeed we believe that the Earth/Moon system was created by just such a collision. We can also see comets crashing into planets to this day. However, the solar system is now much more stable and the major planets now orbit the Sun (because of the Sun's gravity), each following their own orbital path. Each orbital path is separated by millions of miles and while the planets' gravities do tug one on another, this is not enough to destabilize the orbits.
Yes. All planets have gravity. Earth is one of those inner planets.
They believe that the inner planets had gases at one point in time, but the sun burned them away.
