Mercury and Venus are always less than 1 AU from the sun. The Earth's orbit averages 1 AU from the sun, so sometimes the Earth is less than 1 AU, sometimes it is more.
Earth is at times, since 1AU is the average distance. Then theres Mars, Jupiter, Saturn, Uranus and Neptune (being the furthest one out) which are all further than 1AU.
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.
because the farther a planet is from the sun, the longer it takes to make one orbit
they are less than
If we were going to compare any planet to the sun, it would be the gas giant Jupiter. The sun is a couple of hundred times bigger than Jupiter, but the king of the planets is the one that is more similar to the sun than any of the other planets.
he wondered if there was a reason that the planets closest to the sun move faster than the planets farther away.
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.
Mercury
It is because some of the planets are farther from the sun
In our solar system, the planets Mercury and Venus orbit at a distance less than 1 AU. Since the Earth orbits at an "average" distance of one astronomical unit, you might also argue that Earth, owing to orbital eccentricity, sometimes is closer to the Sun than one AU.
there is only one sun in the solar system A Sun is just a star with more than 5 or six planets
because the farther a planet is from the sun, the longer it takes to make one orbit
FAR less. Of all the mass in the solar system, the Sun is 99.5% of it. All the rest - Jupiter included - is one half of one percent of the solar system's mass.
Depends on distance Earth takes one year The two closer planets (Mercury and Venus) take less than a year The other planets take more than a year
it is the 2 planets that are before the earth mercury and venus
all of our planets are heated by the sun. some more, some less! the hottest one would be mercury - being the closest and the coldest one theoretically would be Neptune. Hope this helps

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.
