As your typing your response, I was wondering, where can i findinformation about how far from the sun is voyager 1 and 2 as of january 2,2009 , in meters? I cant find any information on it. Thank you, sorry I know it isnt math related but I cant find any info.

This method is inaccurate.

Find the current speed of voyager 1 and 2. (google)

Find the current distance right now (google)

Now, find the amount of time that has elapsed between Janurary 2, 2009 and right now.

Then do some maths

Hint: Take the elapsed time, multiply by the speed, and the subtract that from the current distance

Sorry, my above answer is inaccurate, not necessarily incorrect.

Time is constantly moving forward, by 1 second each second

So the distance is ever changing if you used my method above.

Easier method:

Find when Voyager 1 and 2 were launched. (google)

Fond elapsed time between initial launch and 2009 januarary 2

Then Mulitply elapse time and speed, done.

From Yahoo ( so....I can't vouch for the reliability)

At 0h UT (Greenwich time) on 2nd January 2009, Voyager 1 was 108.547628513 AU from the Sun. This is 16,238,494,019 km or 10,090,132,389 miles.

Also.....

From, Quora......as of Dec 1, 2017  .....Voyager 2 was traveling at about 34,390 mph= 55,345 km per hour.....it was slightly decelerating all the time

Asuuming that the rate of deceleration is negligible.....there were  11,459 days   between its launch date of 8/20/77 and  01/02/2009

This is 275,016 hrs

So....from the Earth the (rough)  distance traveled (in meters)  =

275,016 hrs * (55,345 * 1000)m  =  15,220,760,520,000 m

And the distance from the Earth to the Sun (on average) is ≈  149,668,992,000 m

So.....on Jan 2,2009......Voyager 2 was about   15,370,429,512,000 m from the Sun

Yes, CPhill calculated it!

Why is the universe so big, but small at the same time.

I am going to have to make sure on the distances and all, but I can always jsut switch out the values since you have gave me the equations! Thank you.

I am curious as to why you included the part in bold

275,016 hrs * (55,345 * 1000)m  =  15,220,760,520,000 m

And the distance from the Earth to the Sun (on average) is ≈  149,668,992,000 m

So.....on Jan 2,2009......Voyager 2 was about   15,370,429,512,000 m from the Sun

Do i subtract the dsitance from earth to sun on average by the 15,220,760,520,000 m to get the final answer that is underlined?

No.....the first distance given  (  15,220,760,520,000 m )  =  the distance Voyager 2 was from the Earth as of 1/2/2009

We must add the distance from the Sun to the Earth ( 149,668,992,000 m)  to get the final distance that Voyager 2 was from the Sun as of this date = 15,370,429,512,000 m

When I first solved it by adding i got a different value so I was confused, but now resolving it I did get the same value. I just wanted to make sure! Thanks(:
