Why the planets seemed to move at different speeds?

What was ptolemys explanation for why the planets seemed to move at different speeds?

The planets move on little circles that move on bigger circles.

How fast does a dwarf planet move?

The question is meaningless; different dwarf planets move at different speeds.

How did ptolemy explain the way planets seemed to move at different speeds and even backwards?

Ptolemy explained the apparent retrograde motion of planets through his geocentric model, where Earth is at the center of the universe. He introduced the concept of epicycles, where planets move in small circles (epicycles) along larger circular orbits (deferents) around the Earth. This model allowed him to account for the varying speeds and occasional backward motion of planets as observed from Earth, creating a complex but comprehensive system that matched the astronomical observations of his time.

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.

Do winds move at different speeds?

Yes.

How do you calculate current position of the planets using Microsoft Excel?

You would need to know a lot about astronomy and the ways the planets are arranged and how they move. That would be your starting point. That would be quite complex. Once you have those calculations, then it could be done in Excel. However the planets are constantly moving, and all at different speeds and taking different amounts of time to orbit the Sun and having various quirks into their movements.You would need to know a lot about astronomy and the ways the planets are arranged and how they move.

What is the speed of planets?

The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.

What was Ptolemy's explanation for why the plants seemed to move at different speends?

because the sun has to be at a different angle to make it move

Can i Move planets across states?

Planets naturally move in our sky over time and therefore are over different states.

Who attributed to the idea that planets do not move at constant speeds in their orbits?

The idea that planets do not move at constant speeds in their orbits is attributed to Johannes Kepler. He formulated his laws of planetary motion in the early 17th century, with his second law, known as the law of areas, stating that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This implies that planets move faster when they are closer to the Sun and slower when they are farther away, indicating non-uniform orbital speeds.

Is it possible for all the planets to align in our solar system?

Yes, it is theoretically possible for all the planets in our solar system to align, but it is extremely rare due to the different orbits and speeds at which they move. The last time all the planets aligned in a straight line was in 561 BC, and the next alignment of all the planets is not expected to occur for several centuries.

Why does each planet in the solar system have a different length of year?

All the planets in the solar system move at different speeds around the sun, and at different distances. The term "year" as in one orbit around the sun has nothing to do with a "year" as a unit of measurement on Earth.
