## What is its average distance semimajor axis from the Sun How does its average distance compare to that of Pluto?

What is its average distance (semi-major axis) from the Sun? How does its average distance compare to that of Pluto? **67.69 AU**; since the average distance for Pluto from the Sun is 39.3 AU then the distance is nearly twice.

## How do you find the average distance of a semimajor axis?

To find the semi-major axis a, we can use the formula **p2 = a3 (with units of years and AU)**. If the period of the comet is 76.0 years, a = p2/3, which gives a = 17.9 AU. The perihelion and aphelion distances are calculated by d = a(1 − e) and d = a(1 + e), respectively.

## How do you find a planet’s average distance from the Sun?

**(a + e) + (a − e) 2 = 2a 2 = a**. So its average distance to the sun is the same as the length of its semimajor axis. From now on, the AU will refer to the length of the earth's semimajor axis. It wasn't until the 19th century that the AU was measured with any sort of remark- able accuracy.

## How do you find the semimajor axis?

The semi-major axis is half of the major axis. To find the length of the semi-major axis, we can use the following formula: **Length of the semi-major axis = (AF + AG) / 2**, where A is any point on the ellipse, and F and G are the foci of the ellipse.
