Only the two inner planets can move across the Sun. Mercury and Venus can pass between us and the Sun and we see a small black circle moving across the Sun's disk, which takes 3-4 hours, and that is a transit.
The other planets go round behind us relative to the Sun and have an opposition instead.
Yes. Neptune orbits the sun.
gravity... i think
Same way as the Earth, since they move together.
None. All eight planets in the Solar System revolve around the sun.
There is 8 planets in our solar system. There was once 9 before Pluto was reclassified as a dwarf planet.
Because of the rotation of the planet and the view.
They appear to move across the sky because of the position of the viewer on a rotating planet with a moving field of view.
The Sun doesn't: "move across the sky" Earth revolves around the Sun which is why it appears to "move across the sky".
the sun dosent move across the sky
the sun
The Earth's rotation causes the sun and moon to 'rise' and 'set. The rotation also causes the sun and moon to move across the sky from east to west, but really this is an illusion we see on out planet.
The planets move in an act of gravity
They all do, its one of the things that is required for a planet to be a planet, directly orbiting the sun.
That planet will move faster in its orbit.
Near the Sun the force of gravity is very strong so the planet has more energy which means it has to move faster.
The Sun's gravity causes a planet to move in its orbit. The Sun's gravity provides a centripetal force. The effects of the Sun's gravity, combined with the planet's inertia (tendency to move in a straight line), results in a planet's elliptical orbit.
Pluto is the slowest planet to move around the sun, because of its far distance.
