Compute r_per and r_ap for the orbit of Planet X, which has eccentricity e = $a, and semi-major axis from the table below.

Planet	Mercury	Venus	Earth	Planet X
a (10¹⁰ m)	5.79	10.8	15.0	$b
T (years)	0.241	0.615	1.00	1.88

1.2 Step 1

Question Sequence

Question 1.1

Recall how r_per and r_ap are related to the semimajor axis, a, and the eccentricity, e.

r_per = a(1 − e)

r_ap = a(1 + e)

Find the length of the semimajor axis of the orbit of Planet X, a, from the table.

a = iSba6t70dtA= × 10¹⁰

Correct.

Incorrect.

1.3 Step 2

Question Sequence

Question 1.2

Substitute appropriately the values of a and e to find r_per, the shortest distance, and r_ap, the longest distance. (Round the decimal value to four decimal places.)

r_per = $b × 10¹⁰(1 9DxysKU6P+4= $a) = U2GIbglD1oM= × 10¹¹ km

r_per = $b × 10¹⁰(1 brSjF5lOKMQ= $a) = or6dmYWrEbA= × 10¹¹ km

Correct.

Incorrect.
