Question

Halp!

Answer 1

Many comets have elliptical orbits with the sun at focus. in many cases the eccentricity is cose to 1 and the ellipse is very flat. halley's comet has an elliptical orbit with eccentricity e=0.967. The closest that halley's comet comes to the sun is 0.587 AU. Approximate the max distance of the comet from the sun in AU, accurate to three decimal places. Note that one astronomical unit = 1AU = (approximately) 93,000,000miles

Answer 2

I'm not sure where to even start...

Answer 3

@zepdrix any ideas?

Answer 4

Mmmm no :x I don't remember eccentricity, sec i try to read

Answer 5

\[e=\frac{c}{a}\]

Answer 6

yep yep. I'm not sure how to apply formulas here hah

Answer 7

I really don't know o.0 i've been trying to manipulate it but it's not working much.
