Pluto has a moderately eccentric and inclined orbit, ranging from 30 to 49 astronomical units (4.5 to 7.3 billion kilometres; 2.8 to 4.6 billion miles) from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its orbital distance of 39.5 AU (5.91 billion km; 3.67 billion mi).
For example, planets in a 2:3 orbital resonance (such as plutinos relative to Neptune) will vary in distance by (2/3) 2/3 = −23.69% and +31.04% relative to one another. 2 Ceres and Pluto are dwarf planets rather than major planets.
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
4.4 Tm – 29.4 au – perihelion distance of Pluto; 4.5 Tm – 30.1 au – average distance between Neptune and the Sun; 4.5 Tm – 30.1 au – inner radius of the Kuiper belt; 5.7 Tm – 38.1 au – perihelion distance of Eris; 6.0 Tm – 40.5 au – distance from Earth at which the Pale Blue Dot photograph was taken. 7.3 Tm – 48.8 au ...
For decades, students learned the phrase "My Very Educated Mother Just Served Us Nine Pizzas" to remember the order of the planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn ...
Five planets are going to be retrograde in the summer of 2024. Here are the dates for Mercury retrograde, Venus retrograde, Saturn retrograde, Neptune retrograde, Pluto retrograde and more.
One consequence of these resonances is that a separation of at least 30 AU is maintained when Pluto crosses Neptune's orbit. The minimum separation between the two bodies overall is 17 AU, while the minimum separation between Pluto and Uranus is just 11 AU [31] (see Pluto's orbit for detailed explanation and graphs).
Pluto belongs to a group of objects that distantly orbit the sun called the Kuiper Belt, where thousands of icy remnants left over from the formation of the solar system linger. Eight of the 10 ...
