In Depth Neptune – NASA Solar System Exploration
WebNeptune's 164-year orbital period means that the planet takes an average of 13 years to move through each constellation of the zodiac. In 2011, it completed its first full orbit of the Sun since being discovered and … The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun). Since planets in the Solar System are in nearly circular orbits their individual orbital velocities do not vary much. Being closest to the Sun and having the most eccentric orbit, Mercury's orbital speed varies from about 59 km/s at perihelion to 39 km/s at aphelion. someone\u0027s knocking at your door

WebLHS 475 b is close in size to Earth, at 99% its diameter, but is much hotter, with an equilibrium temperature of 586 K (313 °C; 595 °F). Assuming the planet has little to no atmosphere, its dayside temperature is estimated at 748 K (475 °C; 887 °F). The planet completes an orbit around its star in just two days and is likely tidally locked.

There are a few peculiarities of Pluto's orbit. These are: Its high orbital eccentricity (e = 0.25) causes Pluto's perihelion to be ever so slightly smaller than Neptune's perihelion. Pluto has an orbital resonance with Neptune. Its orbital period is exactly 3/2 of Neptune's. This orbital resonance is the cause of its orbital eccentricity ... someone\u0027s mail keeps coming ok to throw out
