The teams announced their final results from the occultation in October 2011, with an estimated diameter of 2326 ± 12 km. [12] This makes Eris a little smaller than Pluto by area and diameter, which is 2372 ± 4 km across, although Eris is more massive. It also indicates a geometric albedo of 0.96.
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 moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
Dwarf planet Eris, similar in size to its better-known cosmic cousin Pluto, has remained an enigma since being discovered in 2005 lurking in the solar system's far reaches. While Pluto was ...
Thus the orbital period in low orbit depends only on the density of the central body, regardless of its size. So, for the Earth as the central body (or any other spherically symmetric body with the same mean density, about 5,515 kg/m 3, [2] e.g. Mercury with 5,427 kg/m 3 and Venus with 5,243 kg/m 3) we get: T = 1.41 hours
Eris (13 cm (5.1 in) in diameter) is located at Umestans Företagspark, Umeå, 518 km (322 mi) from the Globe. Made by Theresa Berg , the golden model is inspired by the mythical story of Eris sparking a quarrel between three Greek goddesses with a golden apple bearing the inscription καλλίστῃ ( kallistē , "to the most beautiful one").
Venus has a diameter of 12,103.6 km (7,520.8 mi)—only 638.4 km (396.7 mi) less than Earth's—and its mass is 81.5% of Earth's, making it the third-smallest planet in the Solar System. Conditions on the Venusian surface differ radically from those on Earth because its dense atmosphere is 96.5% carbon dioxide, with most of the remaining 3.5% ...
The flyby of Earth reduced Juice’s speed by 10,737 miles per hour (4.8 kilometers per second) to set it on the path toward Venus and will save the mission around 220 to 330 pounds (100 to 150 ...
