Why do the planets seem to move in a zig- zag pattern through the sky after many weeks?
Retrograde motion. Retrograde motion happens when the Earth moves around the sun faster than the observed planet: the planet is ahead of earth on in its orbit around the sun, but then the earth goes past that planet (in comparison to the sun) and as we go by the planet appears to go backward.
Why are planets also called as wanderers?
The very first astronomers merely looked at night at the stars. They noticed that almost all the stars circled the north star (Polaris) during the night (this is due to the Earth's rotation). Some of the stars seemed to be moving differently, with paths of their own, these were not stars, but were planets.
What 2 planets are in Florida's western night sky?
The two planets in Florida's western night sky are Venus and Jupiter, with Venus being the brighter of the two.
What causes the motion of planets across the sky?
The most commonly discussed "retrograde" motion is the apparent backward motion of a planet caused by its being lapped by another planet, or vice-versa. Both planets move in a direct (eastward) motion around the Sun, but the planet with the inside (smaller) orbit moves faster than the planet on the outside (larger) orbit, and when it passes the slower-moving planet, each sees the other one as apparently moving backwards relative to its usual motion around the sky. In this "retrograde" motion, neither planet is actually moving backwards; it only appears that way, during the time that one laps the other.
Which planet revolves around the sun from west to east and rotates in the same direction in 24 hours?
The planets all revolve round the Sun in an anticlockwise direction as seen from a point to the north of the solar system. Planets always move from west to east in the sky relative to the stars, apart from when they are in retrograde motion.
What is the planets' backwards motion in the sky called?
retrogade motion
What do the planets do to incur retrograde motion?
The planets don't have to "do anything" to "go into" retrograde motion. The retrograde motion, the "moving backward" that planets do as we watch them cross the night sky over the weeks, is due to the nature of the orbit of a planet and to our view of that orbit from earth.
Purpose of using epicycles and deferents to explain the motion of the planets in the night sky was to account?
retrograde motion

What is the app called that if you point it up to the sky it tells you what stars or planets that you are pointing at?
The app is called SkyView.
How do the planets stay in the sky?
planets stay in the sky due to the pull of gravity
What is the region of the sky where the moon and planets appear?
The Moon, Sun and planets all appear in a strip of sky called the ecliptic. It is a plane defined by the plane of the Earth's orbit and the Sun is always on the ecliptic, while the Moon and planets stay close to it.
What is the name given to the phenomenon in which the apparent motion of the planets sometimes reverses?
Retrograde motion happens when the Earth overtakes an outer planet in its orbit. It happens around the date of Opposition when the planet is opposite the Sun in the sky. Usually planets travel from west to east along the ecliptic, but during retrograde motion they travel backwards, from east to west,.
Which three planets occurred in the sky which three planets occured in the sky?
Mars Venus and Saturn
Major advantage of Copernicus' Sun-centered model over the Ptolemaic model?
It offered more natural explanation for the apparent retrograde motion of planets in our sky.
What is retrograde spin?
In astronomy retrograde is essentially a fancy astronomical way of saying backward/ opposite rotational spin. A body is said to have retrograde motion when it rotates in a direction opposite to the body it orbits. I.E. The Sun rotates counterclockwise. Venus has retrograde motion in relation to the Sun because it rotates clockwise.In astrology retrograde refers to the apparent backward motion of a body in the sky due to the Earth overtaking it in orbit about the Sun. Retrograde planets are said to express themselves more internally in a natal chart and in transit indicate periods when the affairs they relate to may resurface to be resolved at a later period when the planet goes direct.
How do you get on the planets in the sky?
You can't
