planets...?

Question

can someone help me plz? i need the radius of orbit around the sun of the 9 planets. does anyone know?? (trying to prove kepler's formula)

just to clarify, i need the RADIUS of orbit (i.e the distance in km),not how long it takes.

Answer 1

This link has a second link to each planet.
At each site, it lists the distance from the sun for each, giving the maximum, minimum, and average.

For your reference, 1 AU = 1 astronomical unit = the average distance that the earth is from the sun.

Answer 2

OK, here we go. :P

Mercury has the most eccentric orbit of the major planets, ranging from 46,000,000 to 70,000,000 km. A Mercurian year is approximately 88 Earth days.

Venus orbits at around 108,000,000km from the Sun. A Venusian year is about 224 Earth days. Oddly, Venus' rotation makes a Venusian day last 243 Earth days - making the day longer than the year.

Earth orbits at around 150,000,000km. A year is approximately 365.25 days.

Mars has an average orbit of 230,000,000km from the Sun. A Martian year lasts about 687 Earth days, or a little under two Earth years.

Jupiter is about 778,000,000km from the sun, and completes an orbit every 11.86 Earth years.

Saturn orbits at around 1,400,000,000km from the Sun, and takes 29.5 Earth years to complete a cycle.

Uranus orbits at around 3,000,000,000km from the Sun, with a year lasting 84 Earth years. You'd be lucky to reach your first birthday there.

Neptune orbits at around 4,500,000,000km from the Sun. I can't find how long that is in Earth years, but the info is out there somewhere. :P

Pluto has the most elliptical orbit, ranging from 4,400,000,000 to 7,400,000,000km, which (yes) brings it closer to the Sun than Neptune sometimes. I think (emphasis on think) that Pluto's orbit takes around 240 years. Ish.

Answer 3

Here are the distances in AU (Astronomical Units). It is a much better unit to use with Kepler's law, if you want (or if you are willing to accept) to get periods in Earth-years.

Mercury: 0.3871
Venus: 0.7233
Earth: 1.0000
Mars: 1.5227

Jupiter: 5.2024
Saturn: 9.5511
Uranus: 19.205
Neptune: 30.159

Bonus:
Pluto: 39.814

If you really need it in km, then multiply everything by 150 million km
(149,597,871 km but so much precision is not needed for Kepler's law).

Answer 4

go to the link provided and the information is in the right hand column under "orbital circumference"
if you then go to the bottom of the page u can do the same for all the planets
:-)
good luck

Answer 5

The orbits don't have a radius as they are elliptical.

Answer 6

at www.nineplanets.org
you can get the distance from the sun
but you have to go to each planet one at a time to get it
all info is in km
multiply by 5/3.1 to get miles

Answer 7

planetary orbital radius look it up online

Answer 8

It takes ______ __ days to orbit.
Mercury 88
Venus 225
Earth 364 and 1/4
Mars 685

It takes ______ ___ years to orbit.
Jupiter 12
Saturn 29
Uranus 84
Neptune 165
