What else can I help you with?
Can planets move by itself?
No, planets cannot move by themselves. Their motion is governed by gravity, which is the force that keeps them in orbit around a star like our sun. This motion is a delicate balance between the planet's velocity and the gravitational pull of the star.
It is now known that the celestial objects which appear to move backwards among the stars are?
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
What is the motion of a asteroid?
They basically move similar to planets and comets, i.e., in ellipses around the Sun.
Which two planets have Retrograde motion?
Venus and Uranus have retrograde rotation.There are other meanings of retrograde motion, but retrograde rotation fits the question best.
Who was the German astronomer who proved that the planets move in oval paths called ellipses?
Johannes Kepler was the German astronomer who proved that the planets move in oval paths called ellipses. His work laid the foundation for the laws of planetary motion.
What is it called when planets move east to west?
Apparent motion of the planets.
Can planets move by itself?
No, planets cannot move by themselves. Their motion is governed by gravity, which is the force that keeps them in orbit around a star like our sun. This motion is a delicate balance between the planet's velocity and the gravitational pull of the star.
Planets move around the sun in orbits?
Yes, planets move around the sun in elliptical orbits due to the gravitational force between the sun and the planet. This motion is governed by Kepler's laws of planetary motion.
It is now known that the celestial objects which appear to move backwards among the stars are?
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
What is the motion of a asteroid?
They basically move similar to planets and comets, i.e., in ellipses around the Sun.
Why do planets appear to move across the sky's star patterns?
Planets appear to move across the sky's star patterns due to the Earth's orbit around the Sun. As we observe other planets from Earth, we are also moving in our orbit, causing the apparent motion of planets against the backdrop of fixed stars. This is known as planetary motion or retrograde motion, depending on the relative positions of Earth and the other planet.
Do all planets stay in one place or do they revolve in orbit?
The planets turn about their axes (rotate), and move in orbits about the sun (revolve). They are all in dynamic motion all the time. Welcome to the music of the spheres. Planets (all of them) are continually in motion. They all revolve on their axes and move about the sun in their orbits. This is the music of the spheres.
What was Ptomeny trying to explain in his model by having the planets move on smaller circles that move on bigger circles?
to explain the motion of planets, especially the phenomenon of retrograde motion where planets appear to temporarily reverse their direction of motion. Ref: Andrew Liddle "An Introduction to modern Cosmology".
Why do planets appear to move through the background of stars?
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
Compared to the background of constellations planets?
Compared to the background of constellations, planets mostly move eastward. Retrograde motion refers to the brief periods of westward movement.
Why do planets wander?
The ancient Greeks called planets 'wanderers' because they appear to move through ther skies in relation to the 'fixed' stars. The apparent movement is because the planets are much closer to the Earth than the stars, and all planets rotate around the Sun, thus all move in relation to each other.
Is reciprocating a motion?
A Reciprocating motion is a up and down or back and forth motion in objects. as we move a saw in a back and forth movement it is a Reciprocating Motion. I got this ans. after doing research in Reciprocating motion in 7th grade
