## 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.

## What is the distance of Pluto from the Sun?

3.7 billion miles Orbit and Rotation But on average, Pluto is **3.7 billion miles (5.9 billion kilometers)** away from the Sun, or 39 AU. From 1979 to 1999, Pluto was near perihelion, when it is closest to the Sun. During this time, Pluto was actually closer to the Sun than Neptune.

## 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.

## What is 50 AU from the Sun?

NASA's New Horizons spacecraft achieved a major milestone on Saturday, April 17, when it reached a distance of 50 AU (astronomical units, with one AU equal to the average Earth-Sun distance or 93 million miles or 150 million kilometers), meaning it is now **50 times as far from the Sun than the Earth**.

## How many miles is Ceres from the Sun?

257 million miles Size and Distance From an average distance of **257 million miles** (413 million kilometers), Ceres is 2.8 astronomical units away from the Sun.

## What is the semimajor axis of ISS?

ISS. The International Space Station has an orbital period of 91.74 minutes (5504 s), hence by Kepler's Third Law the semi-major axis of its orbit is **6,738 km**.

## What is the orbital period in years of a planet with a semimajor axis of 10 AU?

1.7 years c) mars. d) Jupiter. 14) A planet has a semimajor axis of 10 AU. The orbital period would be a) **1.7 years**.

## What is average distance?

-The average distance is **the expectation value of the distance of an electron from the nucleus** i.e. if the radius of the first Bohr orbit is ({a_0}) , the average distance of an electron from the nucleus in the 1s orbital of a hydrogen atom can be calculated by the formula (r = 0.529 times dfrac{{{n^2}}}{Z}mathop …

## What is the meaning of average distance?

noun. **the average of the greatest and least distances of a celestial body from its primary**. **Slang**. Emoji. Acronyms.

## How do you find the average orbital distance?

Formula: **P2=ka3** where: P = period of the orbit, measured in units of time. a = average distance of the object, measured in units of distance….**Formula: F = G M1M2/R2 where:**

- F = force of gravity.
- M1,M2 = masses of the objects involved.
- R = distance between their centers of mass (usually just their centers)
- G = a constant.

## How many miles is the Earth’s orbit around the sun?

92.96 million mi Earth orbits the Sun at an average distance of 149.60 million km (**92.96 million mi**) in a counterclockwise direction as viewed from above the Northern Hemisphere.

## What is the semimajor axis from the Sun?

For example, the semi-major axis of Earth in its orbit around the Sun is **149,598,023 km (or 92,955,902 miles)**, a value essentially equivalent to one Astronomical Unit or 'AU'. In reality, Earth's orbit is slightly elliptical, so its actual distance from the Sun can vary up to some 2,500,000 km from this base value.
