nothing at all. only inertia moving it forward
That's not possible a star is a sun, planets revolve around a star, and the planet would be destroyed far far far far far before the star reached it, if that was even possible
Pluto has yet to be visited by a spacecraft because it is so far away.
No. To start off, the sun is a star, not a planet and is far larger than any planet. The sun is larger than the average star, but it is nowhere near being the largest.
because they shiny and they are far from the earth
A galaxy is larger by far.
as far as i know you cant
The first planet to be visited by spacecraft was Venus. The Soviet spacecraft Venera 1 was the first to fly by Venus in 1961, followed by flybys and landings by subsequent missions from various countries.
as far as i know, it is the hottest planet in the solar system
No, "pulto" is not a known planet in our solar system or in any other known star system.
It seems there is a planet with this name in Star Trek. This would be a ficticious planet, and I believe it is very likely that the creators of the series didn't specify the distance from Earth.
A planetary year is defined as the time it take a planet to make one orbit around its star. The closer a planet is to its star the smaller the diameter of the circle of its orbit. In other words it has less far to go to make an orbit. Thus the length of a year is linked to how far out from the star the planet orbits.
The sun is not a planet, it is a star. As far as stars go our sun is larger than averages, but nothing extraordinary.
