How big are the planets orbits?

How big are the planets orbits?

What are the orbital lengths and distances of objects in our solar system?

OBJECT Distance from Sun (average) Amount of time for one complete orbit of the Sun (one “year.”)
Sun 0 miles
Mercury 36,800,000 miles 3 Earth months
Venus 67,200,000 miles 7 Earth months
Earth 93,000,000 miles 1 Earth year (365.25 days)

How many km is the orbit?

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….Events in the orbit.

epoch J2000.0
period 365.256363004 days
average orbital speed 29.78 km/s (18.50 mi/s) 107,208 km/h (66,616 mph)

What is the orbit of each planet?

The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth’s orbit).

What is Saturn’s orbit distance?

887 million miles
Saturn orbits the Sun at a mean distance of 1,427,000,000 km (887 million miles). Its closest distance to Earth is about 1.2 billion km (746 million miles), and its phase angle—the angle that it makes with the Sun and Earth—never exceeds about 6°.

What planet has shortest orbit?

The planet with the shortest orbital period (year) is Mercury. The innermost planet in our Solar System completes its eliptical orbit around the Sun once every 87 (Earth) days 21 hours.

Which planet has the fastest orbit?

But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

How long is Saturn’s orbit?

29 yearsSaturn / Orbital period
Orbit and Rotation One day on Saturn takes only 10.7 hours (the time it takes for Saturn to rotate or spin around once), and Saturn makes a complete orbit around the Sun (a year in Saturnian time) in about 29.4 Earth years (10,756 Earth days).

What is the slowest orbiting planet?

Venus is the slowest – it rotates once every 243 days —- by far the slowest rotation period of any of the major planets. Sun is the nearest star. Planet with the slowest rotation: Venus.

How do you calculate the orbital period of a planet?

Get the central body density.

  • Multiply the central body density with the gravitational constant.
  • Divide 3π by the product and apply square root to the result.
  • The result is the satellite around central sphere orbital period.
  • What are the actual orbits of the planets?
