What is the orbit size of Neptune?
Orbital characteristics Neptune’s elliptical, oval-shaped orbit keeps the planet an average distance from the sun of almost 2.8 billion miles (4.5 billion kilometers), or roughly 30 times as far away as Earth, making it invisible to the naked eye.
How big is Neptune in astronomical units?
30 astronomical units
Size and Distance If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.
Which planet has the smallest astronomical unit?
| Planet (or Dwarf Planet) | Distance from the Sun (Astronomical Units miles km) | Number of Moons |
|---|---|---|
| Mercury | 0.39 AU, 36 million miles 57.9 million km | 0 |
| Venus | 0.723 AU 67.2 million miles 108.2 million km | 0 |
| Earth | 1 AU 93 million miles 149.6 million km | 1 |
| Mars | 1.524 AU 141.6 million miles 227.9 million km | 2 |
Which planets orbit is larger?

What is the size and diameter of Neptune?
30,599 mi
Neptune/Diameter
Is Neptune big or small?
Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers).
What is the size of Neptune in diameter?
What’s the biggest dwarf planet?
Pluto
Eris is one of the largest known dwarf planets in our solar system. It’s about the same size as Pluto but is three times farther from the Sun. At first, Eris appeared to be larger than Pluto.
Which planet has the shortest orbit?
Mercury
Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun’s planets….Mercury (planet)

How many astronomical units is Neptune away from the Sun?
From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes sunlight 4 hours to travel from the Sun to Neptune. A 3D model of Neptune, an ice giant planet.
How long does it take Neptune to orbit around the Sun?
One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once). And Neptune makes a complete orbit around the Sun (a year in Neptunian time) in about 165 Earth years (60,190 Earth days). Sometimes Neptune is even farther from the Sun than dwarf planet Pluto.
How big is one astronomical unit ( AU )?
More exactly, one astronomical unit (AU) = 92,955,807 miles (149,597,871 km). Earth’s orbit around the sun isn’t a perfect circle. So Earth’s distance from the sun changes throughout the year.
What is the average distance between the planets?
There is a huge amount of different in the distances between the planets depending on their position on their orbit path. The table below shows the eight planets and the average distance between them. The AU column is the distance in astronomical units. 1 AU is the distance from the Sun to Earth, which is 149,600,000 km.
