Rotation (i.e. how long it takes to turn around once - a day or 24 hours roughly) and
Revolution (i.e. how long it takes to move around the Sun once - a year or 365.25 days approximately).

Did Tycho Brahe came to the wrong conclusions about motions of the planets. true or false?
did Tycho Brahe came to the wrong conclusion about motions of the planets. true or false?
Whast were the spheres of Eudoxus?
A mathematical representation of the orbits of the planets, configured in a way that planets would have figure eight motions that would partially explain retrograde motions.
Did Kepler accurately described the motions of all the known planets?
yes
Is it true that Tycho Brahe came to the wrong conclusion about the motions of the planets?
false
Which planets' motions were described with epicycles in the Ptolemaic system?
In the Ptolemaic system, the motions of Mercury, Venus, Mars, Jupiter, and Saturn were described with epicycles. These epicycles were small circles that the planets were thought to move in while also orbiting the Earth on larger deferent circles.
Which two motions does earth in space?
The two motions that Earth makes are rotations and revolutions.
Who among the Greek philosophers was the first to create a mathematical model of the motions of the planets?
Ptolemy
Why do planets have circular and elliptical motions in the solar system?
The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.
Did tycho come to the wrong conclusions about the motions of the planets?
Tycho Brahe did not have the wrong conclusion about the motion of the planets. He was in fact very correct about his observations.
What force determines the motions of planets and other objects in the solar system?
The primary force that determines the motions of planets and other objects in the solar system is gravity. This force, described by Newton's law of universal gravitation, causes celestial bodies to attract one another, leading to the orbits of planets around the Sun and the moons around their respective planets. Additionally, Einstein's theory of general relativity refines our understanding of gravity, illustrating how massive objects warp spacetime, further influencing these motions.
Does the sun's mass control the motions of the planets?
Yes, the sun's mass is a crucial factor in controlling the motions of the planets in our solar system. The sun's gravitational force keeps the planets in orbit around it, shaping their paths and governing their speeds. The more massive an object, like the sun, the stronger its gravitational pull on surrounding objects.
What controls the motions of the planets?
The motions of the planets are primarily controlled by gravity, which is the force of attraction between all masses in the universe. In our solar system, the Sun's gravitational pull governs the orbits and movements of the planets. The precise motions of the planets are also influenced by their initial velocities and the conservation of angular momentum.
