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.
The two closer to the sun than the earth, mercury and Venus. The further you go out from the sun, the longer it takes to orbit it.
Mercury, Venus, Earth, and Mars all take less time than Saturn to orbit the sun. Mercury has the shortest orbital period, completing an orbit in about 88 Earth days. Venus takes about 225 Earth days, Earth takes 365 days, and Mars takes about 687 Earth days.
Only the earth orbits the sun once a year. Mars orbits the sun once every 2 years. As you get closer to the sun the planets orbit the sun in less than a year. As you get past Mars, it takes even longer.
Planets closer to the sun than Earth orbit the sun in less than one year (Mercury and Venus), while planets further out from the sun than Earth take longer than a year (Mars, Jupiter, Saturn, Uranus and Neptune). The further out you go, the longer it takes to orbit the sun.
Neptune orbits the Sun (as do most planets) with an elliptical orbit. When the orbit takes the planet closest to the Sun it is moving faster than when it is furthest from the Sun when on an elliptical orbit.
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.
It is closer to 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
A year for a planet is the time it takes for that planet to orbit the sun. Some planets take longer to orbit the sun because they are farther away from the sun than Earth, so those planets have a farther distance to cover to orbit the sun once than the Earth does.
Mercury with 88 daysVenus with 224.7 days
Well, basically different planets take longer to orbit the Sun. For example, Jupiter takes longer to orbit than earth, so Jupiter has a longer year. On Venus, a day lasts longer than a year as it takes longer to spin on its axis that to orbit the sun.
