Outer planets have smaller orbital periods than inner planets?
They are farther away and have larger orbital periods.
How are inner planets characterized?
Inner planets are characterized by their proximity to the sun and their rocky composition. They are also known as terrestrial planets as they have solid surfaces and are made up of mostly rock and metal. Inner planets include Mercury, Venus, Earth, and Mars. They are generally smaller and have shorter orbital periods compared to outer planets.
When do planets orbit a star?
When don't they? If a planet is in orbit around a star, it is in continual orbit. Orbital periods (the lengths of time it takes different planets to complete one orbit) are different from planet to planet, and are related to the distances between the planets and their stars.

Compared to the background of constellations planets?
Compared to the background of constellations, planets mostly move eastward. Retrograde motion refers to the brief periods of westward movement.
What makes Uranus special or interesting compared to other planets?
Uranus' most unique characteristic is that it's "laying on its side." The angle between its orbital plane and its rotational axis is only 7.77°.
How does a planets orbital radius affect its orbital period?
Yes. T = (2pi / sqroot of GM) multiplied by the radius^3/2. A planets mass DOES NOT affect its orbital period. A planets radius DOES affect its orbital period.
Which inner planets have retrograde rotation?
Out of the four, only Venus. Mercury's rotation is very slow though, compared with its orbital period of the sun.
The relationship between the average distance of a planet from the sun and the planets orbital period is described by what?
AUs
An asteroid belt is found between what two planets orbital route?
The majority of asteroids are found between Mars and Jupiter.
How did the planets get there order?
The balance between gravity (attraction to the Sun) and orbital energy (1/2 velocity2 times mass) gives the planets their order.
Why are orbital periods of the moons of the larger planets are so short as compared to Earth's moon?
The orbital period depends upon the distance to, and the mass of, the primary. Jupiter, for example, is much more massive than Earth and a correspondingly greater velocity is required to balance out its gravitational pull, meaning that a satellite orbits Jupiter in a much shorter time than it would orbit Earth if it were at the same distance.
