Small changes in the orbits of planets caused by the gravitational pull of the other planets in the solar system are called?
Perturbations. These small changes can cause slight variations in a planet's orbital path due to the gravitational influences of other planets.
Comparative essay on the inner planet vs the outer planet?
The inner planets (Mercury, Venus, Earth, Mars) are small, terrestrial planets with solid surfaces, while the outer planets (Jupiter, Saturn, Uranus, Neptune) are gas giants with no solid surface. Inner planets have higher densities and are primarily composed of rock and metal, while outer planets are predominantly made of hydrogen and helium. Additionally, inner planets have shorter orbital periods and are closer to the Sun, while outer planets have longer orbital periods and are further away.
What was the purpose of the epicycle in the Ptolemaic model?
The epicycle in the Ptolemaic model was used to explain the retrograde motion of planets. It involved planets moving on small circular orbits within the larger orbit around Earth. By incorporating epicycles, Ptolemy was able to account for the observed motions of the planets in the night sky.
What do small objects in space have in common?
Small objects that we can detect in space are all in the solar system and they all orbit the Sun and obey Kepler's laws of planetary motion, as do all the planets, asteroids etc.
Are the inner planets small or big?
Small, considering the rest of the planets. But in actuality they are large. As said before, in accordance with the rest of the planets in our Solar system, yes they are small.

Perturbations. These small changes can cause slight variations in a planet's orbital path due to the gravitational influences of other planets.
How do planets change orbital speed change?
Planets with elliptical orbits are affected by the difference in the strength of the Sun's gravity as they move closer to, or farther away from, the Sun. The only other major effect on planets are the gravity of other planets, notably Jupiter and Neptune. Except for Mars, Ceres, Pluto, and trans-Neptunian planets, the effect is extremely small -- it has resulted in stable orbital resonances between several small outer planets and the planet Neptune.
The observed retrograde motion of planets led ptolemy to add blank to Aristotles system?
The observed retrograde motion of planets led Ptolemy to add epicycles to Aristotle's system. Epicycles were small circles that planets moved in on their larger circular orbits around Earth in order to explain the appearances of retrograde motion.

Why are dwarf planets small?
Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?
What are the characteristics of the planets that are closest to the sun?
The planets closest to the sun are Mercury, Venus, Earth, and Mars. These planets are small and rocky, with solid surfaces, and they are known as the terrestrial planets. They have shorter orbital periods and higher average densities compared to the outer gas giants.
What name do you give to the geometric plane where the 8 planets orbit the Sun?
The planets don't all orbit the Sun in EXACTLY the same plane - there are small variations. The plane where Earth orbits is called the Ecliptic; other planets orbit fairly close to that same plane.
Why do planets take different times to revolve around the sun?
The planets in our solar system all orbit (revolve) around the sun on a plane called the ecliptic plane but each of their individual orbits has a different perimeter ranging from small (which would be the closest to the sun) to big (which would be further away from the sun). Since Mercury has the smallest perimeter of orbit, it is the closest planet to the sun and is thus more drawn by the suns gravitational force, both its small perimeter and strong gravitational pull make it revolve around the sun faster, and the bigger the planets orbital perimeter is the further away from the sun it is and the slower its orbit is.

What were epicycles used to describe?
Epicycles were used in ancient astronomy to explain planetary motion within a geocentric model. They involved the idea of planets moving in small circles (epicycles) while also moving along a larger path around the Earth.
Who proposed a mechanical universe with small solid masses in motion?
Rene Descartes proposed a mechanical universe with small solid masses in motion. He believed that all natural phenomena, including the motion of planets and stars, could be explained through the interaction of these small solid masses.
What causes planets to orbit a star?
By the very act of orbiting it. The effect may be incredibly small, but it is real. Any two bodies in an orbital relationship are really orbiting their mutual center of gravity, called their barycenter. This is true even if there are several planets orbiting a star.
