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.
Why do planets move across the night sky but stars don't?
The planets are closer. (They all move - and differently.)
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.
What evidence do you have that the planets move in elliptical orbits around the sun and not in circular orbits?
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
How does a planet move across the sun?
Only the two inner planets can move across the Sun. Mercury and Venus can pass between us and the Sun and we see a small black circle moving across the Sun's disk, which takes 3-4 hours, and that is a transit. The other planets go round behind us relative to the Sun and have an opposition instead.
How do scientist know when intense storms move across the surface of neptune?
Scientist know this by the color difference on the planets surface.
How do planets move and what keeps them in place?
Planets move away by gravity not holding it together and also gravity holds planets together
What is the theory by which all planets move around sun?
The theory that describes how all planets move around the Sun is called the heliocentric model. This model was proposed by Nicolaus Copernicus in the 16th century and states that the Sun is at the center of the solar system, with the planets orbiting around it in elliptical paths.
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 air masses move across the US?
In the United States air masses move across the country by air currents. These air currents are pushed by either hot or cold air masses.
Do inner planets move?
Yes. All planets move in orbit around their host star.
New settlers moved west of the Appalachian mountains to find what?
To move across the United States.
