Why is a Neptunian year much longer than a year on earth?
A Neptunian year is much longer than a year on Earth because Neptune is significantly farther from the Sun, resulting in a longer orbital path. It takes Neptune about 165 Earth years to complete one orbit around the Sun, due to its greater distance and slower orbital speed. In contrast, Earth orbits the Sun in just one year, as it is much closer and moves faster in its orbit. This vast difference in distance and orbital dynamics accounts for the length of a year on each planet.
How long is a day in neputune?
A day on Neptune, also known as a "Neptunian day," is about 16 Earth hours and 6 Earth minutes long. It rotates quickly on its axis compared to Earth, resulting in shorter days.
How many days does Neptune have in a month?
a day is 256 earth days so times that by 30 is 30x256=7680 so about 7680 days
What is the length of a year an day on neptune in earth years?
Each day on Neptune takes 19.1 Earth hours. A year on Neptune takes 164.8 Earth years; it takes almost 165 Earth years for Neptune to orbit the sun once. Since Neptune was discovered in 1846, it has not yet completed a single revolution around the sun.
What is the orbital speed of Sedna?
Its speed will vary greatly as its orbit is highly eccentric. It will be slower when further out from the sun on its 11,000 year orbit. Its average speed is around 1.04 km/s.
Are the Trans-Neptunian objects part of the solar system?
Yes.
How long is a day in neputune?
A day on Neptune, also known as a "Neptunian day," is about 16 Earth hours and 6 Earth minutes long. It rotates quickly on its axis compared to Earth, resulting in shorter days.
Is a Cis-Neptunian object an object that orbits between the Sun and Neptune?
Yes. The prefix "cis" stands for "within" and "trans" means "outside". So, "cis-Neptunian" means "inside Neptune's orbit".
Which words are synonymous with marine?
Maritime, aquatic, Neptunian, nautical, seafaring, oceanic...
What planet takes the most amount of time to orbit the sun?
As Pluto is no longer considered a planet, the planet with the longest orbital period is Neptune. The Neptunian year is approximately 60,190 Earth days.
What are all objects orbiting the sun beyond Neptune known as?
Trans Neptunian Objects.
How many days does Neptune have in a month?
a day is 256 earth days so times that by 30 is 30x256=7680 so about 7680 days
What is a trans-neptunian?
It is any natural body past the orbit of Neptune. (e.g. Pluto, Eris, Sedna)
What percent of the Neptunian atmosphere is helium?
Planet Neptune's atmosphere comprises approximately 19% helium (±3.2%).
What has the author David P Todd written?

How long does it take each planet to orbit the sun in earth days and its own?
Number of Earth Days (and Earth Years) It Takes Each Planet to Complete One Solar Orbit: ------------------------------------------------------------------------------------------------------------------ Mercury - 87.9691 days (0.240851 year) Venus - 224.698 days (0.615203 year) Earth - 365.25636 days (1.000039 years) Mars - 686.971 days (1.880864 years) Jupiter - 4332.59 days (11.86224 years) Saturn - 10,759.22 days (29.45777 years) Uranus - 30,799.095 days (84.32513 years) Neptune - 60,190.03 days (164.7948 years) One Mercurian year lasts 0.49999 Mercurian day (one Mercurian day lasts two Mercurian years). One Venusian year lasts 1.92461 Venusian days. One Martian year lasts 668.591639 Martian days. One Jovian year lasts 10,475.91235 Jovian days. One Saturnian year lasts 24,491.42713 Saturnian days. One Uranian year lasts 42,876.46114 Uranian days. One Neptunian year lasts 89,668.57356 Neptunian days.
Why did they call Pluto a trans-neptunian object?
Because it spends most of its orbital period farther from the sun than Neptune is.
