What is the main difference between the orbits of the inner and outer planets?
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
Which term best describes the shape of the orbits of the planets in our solar system?
The shape of the orbits of the planets in our solar system is best described as elliptical. This means that the paths of the planets around the Sun are elongated circles, rather than perfect circles. The elliptical nature of these orbits is a result of gravitational forces and was first described by Johannes Kepler in the early 17th century.
Do the inner planets have closely spaced orbits?
Yes, the inner planets—Mercury, Venus, Earth, and Mars—have relatively closely spaced orbits compared to the outer planets. Their orbits are tighter and more compact, primarily due to their proximity to the Sun. This results in shorter orbital periods and smaller average distances between their orbits compared to the larger, more distant orbits of the outer planets.
What shapes are the orbits of many comets?
Most cross orbits of planets which allows it to hit the planets easier. They do not go into a full orbit at all.
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.
Which scientist explained why planets orbit the sun and moons orbit the planets?
ANSWER Sir Isak Newton was the first person to realise that the force of gravity was universal. It is Kepler motion that describes the elliptically orbits of 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.
What are the four planets that have orbits from most to least?
All the planets have orbits so four cannot be picked out.
What of the planets are ellipses?
their orbits
Why planets and moons of planets stay in their orbits?
The forces of gravity between two masses are the cause of all orbits.
Kepler showed that the orbits of the planets are?
Kepler showed that the orbits of the planets are elliptical, with the Sun at one of the focal points. This discovery led to his laws of planetary motion, which describe how planets move in their orbits.
Do all planets have eliptical orbits?
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
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 the path planets travel?
Planets travel in elliptical orbits.
