Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
What does a longer orbital period mean?
Result: a more distant planet must orbit the Sun at a lower average orbital speed. Slower orbital speed and a larger orbit mean that its orbital period must be longer!
Which object has the longest orbital period?
Which planet has the longest orbital period? Answer: Neptune has the longest orbital period of 60,190 days.
What exoplanet has the longest orbital period?
This artist’s conception shows Kepler-421b , a Uranus-sized transiting exoplanet with the longest known year, circling its star once every 704 days. Kepler-421b orbits an orange, K-type star that is cooler and dimmer than our sun and is located about 1,000 light-years from Earth.
What has the shortest orbital period?
A hot Earth
The shortest confirmed orbital period is 10.9 hours, which belongs to Kepler-42c, while the shortest unconfirmed one (held by a planet candidate called KOI 1843) is only 4.3 hours.
Which planet has the most moons?
| Planet / Dwarf Planet Confirmed Moons Total | Jupiter 53 79 | Saturn 53 82 | Uranus 27 27 | Neptune 14 14 |

Is Eris bigger than 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. ... Pluto, Eris, and other similar objects are now classified as dwarf planets.
What does orbital period depend on?
The orbital period of a satellite depends on the mass of the planet being orbited and the distance of the satellite from the centre of the planet .
What is the orbital period of the moon?
Near and far sides of the moon
The moon orbits the Earth once every 27.322 days . It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still.
What star has the most exoplanets?
The star with the most candidate planets is HD 10180 , with a maximum of 9 planets – 6 confirmed and 3 candidates.
What is the least known planet?
Scientists have found the smallest known planet — smaller than Mercury , the smallest planet in Earth’s solar system.
Which exoplanet is least massive?
“ Withonly 1.9 Earth-masses , it is the least massive exoplanet ever detected and is,very likely, a rocky planet,”said Xavier Bonfils of Grenoble Observatory inFrance, a member of the team that made the discovery, which was announced atthe European Week of Astronomy and Space Science at the University ofHertfordshire in ...
What planet takes 7 years to orbit the sun?
| 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) |

Which planet is the slowest to orbit the sun?
A Year On Venus :
In fact, Venus takes 243 Earth days to rotate once on its axis – the slowest rotation of any planet – and its rotation is retrograde to its orbital path.
What planet rotates the fastest?
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
