The average distance between Neptune and the Sun is 4.5 billion km (about 30.1 astronomical units (AU), the mean distance from the Earth to the Sun), and it completes an orbit on average every 164.79 years, subject to a variability of around ±0.1 years. The perihelion distance is 29.81 AU, and the aphelion distance is 30.33 AU.
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).
Geostationary Earth Orbit is 42,164 km (26,199 mi) from Earth center, or 1 / 9.117 LD = 0.109 68 LD (or 0.109 68 LDEO [19]) Distance between the Earth and Moon ( mean value ) – sizes and distance to scale – with travel time at speed of light animated Photo of Earth and Moon , taken by the OSIRIS-REx probe Lunar distance to scale ...
New Horizons is traveling through the Kuiper belt; it is 60.99 AU (9.12 billion km; 5.67 billion mi) from Earth and 60.37 AU (9.03 billion km; 5.61 billion mi) from the Sun as of November 2024. [27] NASA has announced it is to extend operations for New Horizons until the spacecraft exits the Kuiper belt, which is expected to occur between 2028 ...
The semi-major axis of the geocentric lunar orbit, called the lunar distance, is approximately 400,000 km (250,000 miles or 1.28 light-seconds), comparable to going around Earth 9.5 times. [ 178 ] The Moon makes a complete orbit around Earth with respect to the fixed stars, its sidereal period , about once every 27.3 days.
This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...
The largest such scale model, the Sweden Solar System, uses the 110-meter (361-foot) Avicii Arena in Stockholm as its substitute Sun, and, following the scale, Jupiter is a 7.5-meter (25-foot) sphere at Stockholm Arlanda Airport, 40 km (25 mi) away, whereas the farthest current object, Sedna, is a 10 cm (4 in) sphere in Luleå, 912 km (567 mi ...
