How is the moon different from a planet?
the moons orbit the planet but the planets orbit the sunMoons revolve round planets. Planets revolve round suns.___________AlternateThe truth is that planets orbit round their moons, or more precisely a planet and its moon(s) orbit around their barycenter, the center of gravity of the planet-moon system. This is true for the earth, but this orbital motion of earth is less noticeable than the orbital motion of the smaller moon. I think the real difference between planets and their moons is relative size.
What are some similarities of the inner and outer planets?
Inner and outer planets have some things that are in common but there mostly way different. For instants they both orbit the sun. On the other hand the outer planets are made mostly by gas, that's why they are called the gas giants. The inner planets are mostly made by rock and dust. The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. The outer planets (Jovian Planets) are farther from the sun, they have less density, they have more moons, they are large, about the size of Jupiter, they rotate rapidly, and they have more mass. These planets are alike because they both orbit the sun.
Is mercury an inferior or superior planet?
Yes. The inferior planets not only move faster, but also have a smaller path, to go once around the Sun. So, both of these factors contribute for the interior planets to take less time to go once around the Sun.
Which planet takes the least time to revolve around the sun?
mercury, it only takes 88 days. The closer the planet is to the parent star (sun in our case) the less time it takes to complete one orbit. Mercury is the closest planet to the sun and the planet to take the shortest time to orbit it.
Why do planets take different times to orbit the sun?
Kepler's Third Law of Planetary Motion gives the mathematical formula for this. Isaac Newton proved the Law follows from his theory of gravitation. I will not go into the mathematics, but basically it's just how gravity works with planets.
Why are planets that orbit around the Sun and satellites that orbit around these planets always called ellipses rather than perfect circles?
The planets, and the satellites that orbit around them, are affected by gravity from the sun and other celestial objects. The effects of gravity at different locations during their orbits prevent their orbits from being circular, and they become elliptical (more or less egg-shapped).
Which planets take less than a year to orbit around the sun?
Mercury with 88 daysVenus with 224.7 days
Are astronauts in orbit truly weightless?
no they can weigh more or less depending which planets orbit
What planets' years are less than a earth's day?
There are no solar planets that orbit the Sun in less than 24 hours. The closest, Mercury, takes about 88 days to orbit the Sun.
Where is the ecliptic of the Earth?
The Ecliptic is the plane of Earth's orbit around the Sun. Other planets are also found more or less on the same plane.

What planet travels around the sun in less time than it take earth to complete one orbit?
it is the 2 planets that are before the earth mercury and venus
Why do the planets orbit in many different planes?
The planets in our solar system orbit in different planes because they formed from a rotating disk of gas and dust around the young Sun. The angular momentum of this rotating disk caused the planets to form in different planes. Over time, gravitational interactions between the planets and other celestial bodies can further perturb their orbits, leading to even greater differences in orbital inclinations.
Do comets orbit around the sun just like planets?
Yes, they do. But their orbits are highly eccentric. That means that their orbit first takes them very close to the Sun and then very far away, making the orbit very elongated. Also, all the planets orbit the Sun in more-or-less the same plane. ie, All the orbits are in line (Picture a disc). The orbit of most comets, on the other hand, are not in the same plane. Check the images in the related links for a better idea on their orbits.
Does a comet orbit anything?
Yes, comets orbit the sun, but usually in an eliptical (oval) or eccentric orbit rather than a more-or-less circular one like the planets.

Which planets take less than a year 2 orbit the sun?
Mercury and Venus take less time to orbit the Sun than the Earth does. ummm...if you need 5 then...earth, venus, mercury, mars and jupiter
