Which planet, moon, or constellation has 486 days orbit? (to itd sun or galaxy center) any orbit of 486 days?

I am just looking for a space object with an orbit of 486 days or any one that is a Multiple of 27x9, 27x18, 27x27 days



where can i find thsi information?



Thank youWhich planet, moon, or constellation has 486 days orbit? (to itd sun or galaxy center) any orbit of 486 days?The only possibility would be an asteroid. No moon has an orbital period that long, and constellations don't orbit at all.Which planet, moon, or constellation has 486 days orbit? (to itd sun or galaxy center) any orbit of 486 days?
You could use Kepler's law to find the mean orbiting distance "a" (around our Sun) for such an object:



P^2 = a^3



You have to use the period in Earth-years, and the answer will give you "a" in AU (astronomical units -- the Earth's mean orbital distance is 1 AU).



486 days = 1.33 years

(1.33)^2 = a^3

a = CubeRoot(1.7689) = 1.2094 AU



There is no object that jumps to mind (Earth is at 1 and Mars is at 1.52).



You could go through the list of asteroids. For example, you could concentrate on those that come near Earth, on this list

http://neo.jpl.nasa.gov/cgi-bin/neo_elem



For example, I checked out the "Amors" (asteroids with perigee between the orbit of Mars and Earth) and I found four with a = 1.20 and four with a= 1.21



Two very likely candidates are:

2002 TD60

and

2010 DJ



These two asteroids would have an orbital period very close to 486 days.



We can check at this site:

http://neo.jpl.nasa.gov/orbits/

enter the name (for example 2002 TD60) in the box, then click. Wait for the applet to load.

You can then go directly in the data box below the diagram and read the period directly:

481.4245664837339

(too small)



Try 2010 DJ

period = 484.4681232041272

getting closer



2010 GC35

485.491707943360



2001 WW1

486.2883282722721



and so on.

Hours of fun.

For other planetary system, you should check here:

click on interactive catalog %26gt;%26gt; all candidates

then, once in the table, click on "Period" and it will sort the list by orbital period.



nothing matches 486 (so far); the closest is a planet known by the very poetic name of 46 Dra b

(because it circles the star number 46 in the constellation Draco, the Dragon, located between the Big Bear and the Little Bear),

with a period of 479.1 days.Which planet, moon, or constellation has 486 days orbit? (to itd sun or galaxy center) any orbit of 486 days?None that we know of, I think.



The Earth orbits in 365 days, Mars orbits in 687 days. Any object orbiting the sun in 486 days would have to be between those two planets.



Moons around a planet will orbit much faster. As for the sun orbiting around the galactic center, that takes somewhere around 230 million years, give or take a bit.

Wikipedia or the NASA site is a good start.



As an interesting fact, 486 Earth days is almost exactly how long it takes Venus to rotate twice with respect to the fixed stars.Which planet, moon, or constellation has 486 days orbit? (to itd sun or galaxy center) any orbit of 486 days?I think Mars.
