What can you find between the orbits of the planets in our solar system?
The asteroid belt
The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars.
What are the actual orbits of the planets?
The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth’s orbit).
Which planet orbits exactly on the ecliptic plane?
Sun
As seen from the orbiting Earth, the Sun appears to move with respect to the fixed stars, and the ecliptic is the yearly path the Sun follows on the celestial sphere….Equinoxes and solstices.
| ecliptic | equatorial | |
|---|---|---|
| December solstice | 270° | 18h |
In what direction do the planets revolve around the Sun?
A: The planets of our solar system orbit the Sun in a counterclockwise direction (when viewed from above the Sun’s north pole) because of the way our solar system formed.
What is found in between the orbit of Mars and Jupiter?
main asteroid belt
There are lots of asteroids in our solar system. Most of them are located in the main asteroid belt – a region between the orbits of Mars and Jupiter. Some asteroids go in front of and behind Jupiter. These are called Trojan asteroids.
What determines the orbit of a planet?
In the solar system, the planets follow orbits determined *mainly* by the Sun’s gravity — since the Sun is the *most* massive object in the system (it is about 1000 times as massive as Jupiter, which is about 300 times more massive than Earth). Same for the other planets’ orbits.
How many orbits are there in solar system?
In addition to the eight planets, there are many smaller objects in the solar system. Some of these are moons (natural satellites) that orbit all the planets except Mercury and Venus….Orbits of Asteroids and Comets.

| Semimajor Axis (AU) | 1 | |
| Period (y) | 1.00 | |
| Eccentricity | 0.02 |
Are planets orbits on the same plane?
It makes sense that most large planets in our solar system stay near the ecliptic plane. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.
Do all planets orbit clockwise?
Answer: Most of the objects in our solar system, including the Sun, planets, and asteroids, all rotate counter-clockwise. This is due to the initial conditions in the cloud of gas and dust from which our solar system formed. That rotation just happened to be in a counter-clockwise direction.
What are the planets that orbit the Sun?
Based on this model, the planets Mercury, Venus, Mars, Jupiter, and Saturn all orbit the Sun, which in turn orbits the earth. As it turned out, Kepler, unlike Brahe, believed firmly in the Copernican model of the solar system known as heliocentric, which correctly placed the Sun at its center.
What are the approximate sizes of the planets relative to each other?
This illustration shows the approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, followed by the dwarf planet Pluto. Jupiter’s diameter is about 11 times that of the Earth’s and the Sun’s diameter is about 10 times…
How many planets are there in the Solar System?
Adjust masses, velocities, and positions of the planets, and see what happens to their orbits as a result. In addition to the eight planets, there are many smaller objects in the solar system. Some of these are moons (natural satellites) that orbit all the planets except Mercury and Venus.
How many orbits does it take for each planet to orbit?
Orbit Lengths. In the time it takes the Earth to complete one orbit, the planets closer to the Sun (Mercury and Venus) orbit at least once. The more distant planets (Mars, Jupiter, Saturn, Uranus and Neptune) which move slower and have a greater distance to travel, complete just a fraction of their orbits in this time. Mercury. (4.2 Orbits) Venus.
