Why do different planets have different length orbits?
Different planets have different length orbits because they are at varying distances from the sun. The farther a planet is from the sun, the longer it takes to complete an orbit. This is due to the gravitational pull of the sun, which affects the speed at which planets travel around it.
Does the sun orbit the planets?
No. The planets orbit the Sun and the Sun orbits itself.
What evidence do you have that the planets move in elliptical orbits around the sun and not in circular orbits?
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
Which object's gravity holds the planets in their orbits?
The sun's gravity holds the planets in their orbits. It also holds other space objects in their orbits, such as asteroids.
What is a satellite that orbits the sun?
PLANETS
What orbits the sun and moon?
the planets
What force is responible for the orbits of the planets in the solar system?
Gravity from the Sun holds the planets in their orbits.
Which planet moves the most slowly in its orbit?
Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.
Planets revolve around the sun along?
In one word 'YES'. The paths that you describe are the planets orbits. These orbits are shaped like 'Ellipsoids'., that is an ellipse that doesn't quite close-up , but overloops with every circuit. The Sun lies not at the centre of the ellipsoid, but at one of the foci. As a consequence planets following their orbits paths speed up (Nearest the Sun) and slow down (Furthest from the Sun).
What is the speed of planets?
The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
What planet orbits the sun faster than all other planets?
Mercury - it orbits the Sun once in just 88 Earth days.Mercury's average orbital speed is 47.9 kilometers per second.
Does the speed of planetary orbits increase the closer the planet is to the sun?
Yes, according to Kepler's laws of planetary motion, planets move faster in their orbits when they are closer to the sun. This is due to the gravitational force exerted by the sun, which causes the planet to accelerate as it gets closer.
