Alan thought they would be able to speed past it, but it slid faster than he thought. Within less than a minute, “the rocks, the dirt, everything hit us. It was scary,” he said.
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of the Earth, [1] Venus, Jupiter, Saturn, Uranus, and Neptune. [2] On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Jet streams may start, stop, split into two or more parts, combine into ...
The second wind story is about the extent and severity of Helene’s truly destructive winds, which will occur over a more limited area closer to the center of circulation.
The presence of the Moon (which has about 1/81 the mass of Earth), is slowing Earth's rotation and extending the day by a little under 2 milliseconds every 100 years. Tidal acceleration is an effect of the tidal forces between an orbiting natural satellite (e.g. the Moon) and the primary planet that it orbits (e.g. Earth).
Atmospheric super-rotation is a phenomenon where a planet 's atmosphere rotates faster than the planet itself. This behavior is observed in the atmospheres of Venus, Titan, Jupiter, and Saturn. Venus exhibits the most extreme super-rotation, with its atmosphere circling the planet in four Earth days, much faster than its planet's own rotation.
Deferent and epicycle. The epicycles of the planets in orbit around Earth (Earth at the center). The path-line is the combined motion of the planet's orbit (deferent) around Earth and within the orbit itself (epicycle). In the Hipparchian, Ptolemaic, and Copernican systems of astronomy, the epicycle (from Ancient Greek ἐπίκυκλος ...
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
Because light travels about 300 000 kilometres (186 000 mi) in one second, these measurements of small fractions of a second must be very precise. The Lunar Laser Ranging experiment , radar astronomy and the Deep Space Network determine distances to the Moon, [ 90 ] planets [ 91 ] and spacecraft, [ 92 ] respectively, by measuring round-trip ...
