How long it takes the planet to orbit the sun?
one day
What do you call the amount of time it takes for a planet to orbit the sun?
One round trip around the sun is called a "YEAR".
What is the time it takes for planet to complete 1 orbit around the Sun called?
A year. Any planet, any length of time, for that planet once around the sun is their year.
Is one complete turn of a planet on its axis one day?
Yes, a planet's spin one time on its axis is defined as that planet's day; 24 hours in the case of our Earth. In astronomical circles this is referred to as rotation, distinct from revolution which is applied to the time it takes for the planet to orbit around the Sun, which is that planet's year.
How many days does it take to orbit Mercury?
Mercury is the closest planet to the sun and it is the fastest to orbit the sun. It takes 88 days for the Mercury to completely orbit the sun.
How long it takes the planet to orbit the sun?
one day
Does it takes the sun a year to orbit the earth?
A "year" is the time it takes for the earth to orbit the sun. Each planet has it's own year. A "day" is how long it takes for the planet to spin all the way around.

A year. Any planet, any length of time, for that planet once around the sun is their year.
Which planet has a day that is almost as long as its year?
Venus - it takes 243 days to spin on its axis relative to the background stars, while it takes 224.7 days to orbit the sun.
What does the planets rotation on its axis determine the length of?
Roughly, the day. To be precise, the day also depends slightly on the planet's orbit around the Sun, but if the time it takes for a planet to rotate once is short, compared to the time of an orbit, it won't make much difference. For instance, a day on Earth is 24 hours; the time it takes Earth to rotate once is about 23 hours and 56 minutes.

What is a planet year?
A year by definition is the time it takes a planet to orbit the Sun, therefore a planet year is different depending on what planet you are discussing. a planet closer to the Sun would have a shorter year (less distance to travel) whereas a planet farther from the Sun would have a longer year (more distance to travel)This is the time taken for the planet to orbit once around the sun. An earth year is still an earth year, regardless of what plaet you are on.The period of time that it takes for a planet in our solar system to make a complete revolution around the sun.As such due to their differing orbits this can vary considerably from an 88 day year for Mercury (approx. 1/4 of an Earth year) up to a 90,613 day year for Pluto (approx. 248 Earth years).
Which planet has a year that is shorter than its day?
There is some confusion on this matter. Because of its spin-orbit resonance and fast orbit, an observer on Mercury would see only one day every two years. Venus has the slowest rotational period of any planet in our solar system at 243 days, and it completes an orbit in 224 days, so its sidereal day is longer than its year - but note that because of its retrograde motion (it rotates upside down, or spins the opposite direction it orbits), an observer of Venus would see almost two days per Venusian year, so its solar day is shorter than Mercury's.
What causes the length of a year on a planet?
The length of a year, for any planet, is the amount of time that it takes for that planet to complete one orbit of the sun. That, in turn, depends only upon the distance of that planet from the sun. The closer the planet is to the sun, the shorter the year. The farther the planet is from the sun, the longer the year. It takes a certain amount of orbital speed to counteract the gravitational attraction of the sun. And similarly, if a planet is moving faster in its orbit, there will be correspondingly more centrifugal force, causing the planet to move farther from the sun. Orbital mechanics makes it all work out.
How long does it take for a satellite to orbit round earth?
I believe that is around 90 minutes or about an hour and a half. I'm pretty sure of that.
What do we mean by a year?
When we say "A Year", we mean the number of days it takes for our planet (Earth) to orbit the sun. A year for us is 365.25 days because that is how long it takes for Earth to orbit around the sun. This is also the reason why we have a leap year with one extra day every four years, to make up for the extra 0.25 of a day we don't count when our year/orbit completes.
