I think it is because of the Gravity force between the planets and Sun and other planets

Gravity and Inertia
Inertia- the tendency of an object to resist change.
Inertia is the reason it is hard for a large semi to stop or go, or why when you slam on the brakes, you go forward.
Inertia keeps the plants going in a line and the sun's gravitatioal pull keeps Earth going in a circle.

The Sun is extremely massive, and large bodies attract other bodies (the force of gravity). Planets are falling towards the sun in a spiral motion, going around and around and slightly getting closer with each passing year.

it's beleived to have first started as the "big bang" which cuased a huge explosion and the force of that explosion is still moving the planets, and the gravitaional pull is putting the planets in place

The core of the earth is a molten mass of liquid which is spinning and that is what causes the earth to spin
to demonstrate this take a raw egg spin it on your countertop and stop it and quickly let go and see what happens
this spinning is also what creates the magnetic force that we know as the magnetic feild around the earth

the sun's gravty pulls the planets closer and cloaser. one day every plant will have been consumed by the sun the rate at which it pulls is .001 cm a year. so it will take a long time

Gravity and momentum. Gravity keeps them in a near circular orbit while the speed at which they travel is from left over momentum of the material that condensed and formed them.
