What is a retrogade planet?
A planet isn't retrograde - retrograde means the direction a planet moves in relation to how we see it here on Earth or other perspectives. Planets sometimes appear to move backward due to Earth moving as well.
What is a retrograde loop is astronomy?
You and I, little buddy, are going to take a little ride in my virtual spaceship. Whoosh! Of we go, and moments later, we are poised about 3 AU directly above the north pole of the Sun. We're going to sit here and watch the planets Earth and Mars for a couple of virtual years..... We can see that the Earth is clicking along in its orbit, making one complete circle in 365 1/4 days. Mars is further out from the Sun, so Mars is moving slower and takes nearly two Earth years for one Martian year. We can see that both planets are moving in very slightly elliptical paths; not perfect circles, but close enough. Now, back to Earth! We land on the Earth, and watch the planet Mars through the year. Remember, Earth is still going faster than Mars is, and will overtake the slower planet. So day by day we see Mars moving along through the stars, but it appears to be slowing down! Soon, as the Earth gets close to passing Mars, our view shows us that Mars is REALLY slowing down, and because Earth is moving faster, Mars appears to move backwards among the stars! Then, as Earth gets enough ahead, we see that Mars was moving straight ahead all along; that it looked to be going backwards was a trick, an illusion caused by the fact that the Earth was catching up to Mars in their orbits and pulling ahead. So the whole thing was a trick, caused by our perspective of riding on a moving planet and watching a different planet that was moving in a different way!
Is earth's surface currently moving away from the rest of the planet?
No. The surface of the earth is held to the planet by gravity. However parts of the surface move relative one to another - this is called plate tectonics.
Which planet is the next farthest away from the sun after the earth?
Jupiter is the next proper planet after Mars unless you count the dwarf planet, Ceres. Ceres is the largest object in the asteroid belt.
What is the densest planet?

Who was the person that had a theory that earth was a moving planet?
Copernicus.
What was Nicoluas Copernicus discovory?
He discovered that the Earth is a moving planet
Can you see your planet from earth?
Yes
How fast is planet earth moving?
66,000MPH or 107,200 KM/HR
Which planet is known as the blue planet?
Earth is known as the blue planet because of its extensive oceans that give it a predominantly blue appearance when viewed from space. The reflection of sunlight off the oceans contributes to its blueness.
What causes the motion of a planet like mercury that you see in 24 hours?
The rotation of the earth causes us to think the other planets and stars are moving from east to west.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
What planet can you see without a telescape?
You can see Mercury and Venus. They both look like really bright stars. Since the Earth's always moving their never in the same place and you can't always see them at the same time either.
What planet is the most interesting and why?
The Earth is. It has all these things crawling and moving near its surface.
What planet is moving through space at at a speed of 18.5 miles per second?
Earth.
How can the moon and sun tell us that the earth is moving?
The moon and sun can tell us that the earth is moving as our earth spins adding to the sight of turn of the Moon which we can see in the sky moving throughout the day. The sun can tell us the earth is moving as we can see shadows on people and objects moving around telling us something has to be moving. It has been scientificly proven that is not the Sun or "Sol" so we know it is the Earth.
