These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
The finding is unexpected because comets, not asteroids, are typically considered to "sprout jets and plumes". According to one of the scientists, "The lines are becoming more and more blurred between comets and asteroids." [103] Findings have shown that solar winds can react with the oxygen in the upper layer of the asteroids and create water ...
The number of asteroids brighter than H = 25, which corresponds to about 40 m (130 ft) in diameter, is estimated at 840,000 ± 23,000 —of which about 1.3 percent had been discovered by February 2016; the number of asteroids brighter than H = 30 (larger than 3.5 m (11 ft)) is estimated at 400 ± 100 million—of which about 0.003 percent had ...
Our solar system is full of floating space debris: Comets, meteors, asteroids and more. What are the differences that make up these various space rocks?
Four huge asteroids — and a fifth that's much smaller — are passing Earth on Thursday in their closest approaches to the planet ever recorded. 4 large asteroids, including 1 the size of a ...
First asteroid known to have more than one moon (determined in 2005) 90 Antiope: 80×80: October 1, 1866: Double asteroid with two nearly equal components; its double nature was discovered using adaptive optics in 2000 92 Undina: 126: 1867 July 7: Created in one of the largest asteroid-on-asteroid collisions of the past 100 million years 216 ...
Scientists think a larger comet was gravitationally bound into a short orbit by the sun around 2000 BC. The comet left behind meteors for years before breaking apart sometime between the years 100 ...
Barring detailed mass determinations, [4] the mass can be estimated from the diameter and assumed density values worked out as below. = Besides these estimations, masses can be obtained for the larger asteroids by solving for the perturbations they cause in each other's orbits, [5] or when the asteroid has an orbiting companion of known orbital radius.
