What happen to the planet's orbit if there is no sun?
There would be no orbit. You have to have a body to orbit around and without a star or other planet to orbit around, it would just move in a straight line.
What planet has the most unusual and highly elliptical orbit which causes it to move inside another planet's orbit every 248 years?
You are thinking of Pluto. Pluto is now designated a minor planet.
Inertia makes a plant tend to travel in a straight line but what keeps it in orbit?
Gravity keeps a planet in orbit. Inertia tries to make the planet move in a straight line. The balance between the two makes the planet orbit a sun.
Is Saturn the fastest planet?
It's not at all clear what you mean by the speed of a planet. In terms of its speed of rotation, or the length of its 'day', Saturn is the second fastest, just behind Jupiter. Regarding its speed in orbit around the sun, Saturn is the 6th fastest planet in our solar system. Mercury, Venus, Earth, Mars, Jupiter, and most of the asteroids, all move faster in their orbits virtually all of the time than Saturn does, and several comets do that for part of the time.
Do the planet have orbit?
Each planet is in its own orbit and obey's Kepler's laws of planetary motion. Newton later discovered that the Sun's gravity is what makes the planets move in their orbits in the way they do.
Does a planet moving in an elliptical orbit about the sun move fastest when it is farthest from the sun or when it is nearest to the sun?
nearest to the sun
What happens when a planet moves closer to the sun?
That planet will move faster in its orbit.
What happen to the planet's orbit if there is no sun?
There would be no orbit. You have to have a body to orbit around and without a star or other planet to orbit around, it would just move in a straight line.
When does a planet move slowest in its orbit?
At its aphelion, the point furtherest from its primary while in orbit.
Does every planet move?
Yes. A planet must orbit its star, in our case the sun.
When does a planet move fast or slow?
A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
Do planets travel at the same speed as they orbit the sun?
No. The the planets closest to the sun orbit the fastest. Mercury, the first planet from the sun orbits at about 107,000 mph. Earth orbits at about 65,000 mph, and Neptune, the farthest planet, orbits at about 12,000 mph.
What planet has the most unusual and highly elliptical orbit which causes it to move inside another planet's orbit every 248 years?
You are thinking of Pluto. Pluto is now designated a minor planet.
Pluto's orbit causes this planet to move from ninth and not the eighth?
neptune
What is it called when a planet appears to move bacwards in is orbit?
"retrograde motion"
Why the planet move around the orbit?
the planet moves around the orbit because it is heavy and strong enough to pull its self in a circle around the sun. Thanks!:)
What is the link between the suns gravity and the motion of a planet?
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.
