Can planets move by itself?
Yes. Not so much 'Can they move?' - they are constantly in motion.
What is the motion of a asteroid?
They basically move similar to planets and comets, i.e., in ellipses around the Sun.
How often does Saturn move?
Saturn, as are all other planets, is in a constant state of motion around the Sun.
Why are planets seen in different locations at different times?
Because the planets are closer to us so when we look at the planets we can see them move so the closer an object is to you the easier it is to follow its motion. Hope you could use my answer
Can inferior planets undergo retrograde motion?
The two inner planets Mercury and Venus move in retrograde motion (east to west along the ecliptic) between their time of greatest distance from the Sun (elongation) to the east as an evening star and their greatest elongation west as a morning star.
What is it called when planets move east to west?
Apparent motion of the planets.
Can planets move by itself?
Yes. Not so much 'Can they move?' - they are constantly in motion.
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".
What is retograde motion?
Retrograde motion, as opposed to prograde motion, is moving clockwise while almost all the other planets and moon move counter-clockwise.
What is the motion of a asteroid?
They basically move similar to planets and comets, i.e., in ellipses around the Sun.
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.
How often does Saturn move?
Saturn, as are all other planets, is in a constant state of motion around the Sun.
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.
What men stated that planets move around the sun in an ellipse?
Johannes Kepler in his three laws of planetary motion
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
Why are planets seen in different locations at different times?
Because the planets are closer to us so when we look at the planets we can see them move so the closer an object is to you the easier it is to follow its motion. Hope you could use my answer
How can planet retrograde motion be explained by the Earth-center hypothesis By the Sun-center hypothesis?
In the Geocentric Hypothesis (Earth-centered), retrograde motion can only be explained by describing the motion of planets as complex, curlicue paths. In the Heliocentric Hypothesis (Sun-centered), retrograde motion is described as changes in relative motion as the Earth overtakes a slower-moving planet in an outer orbit, or is overtaken by a faster-moving planet in an inner orbit. In the Heliocentric Hypothesis, all planets move in more-or-less circular orbits at more-or-less constant speeds, but planets closer to the Sun move faster. Thus, the Earth can overtake and pass each of the outer planets, making them appear to move "backward" (retrograde) for a time.
