is the highest of any planet. Its mean density, 0.7 times that of water, is lower than that of any other planet. Before 1978 Saturn was thought to have 10 satellites, the three largest being Titan, Rhea, and Iapetus; the number is currently 47. Orbital and physical characteristics of pla...
Maximum number of items per order is 500. Orders listing more than 500 itemIds have to be split, and subscriptions must be used instead of search-based orders that match more than 500 items. Minimum individual order is 1 hectare, and is subject to some shape constraints. You can order to...
At a maximum, the entire planet can be colonized and terraformed. But for a first colony, I'd suggest targeting a hotspot volcano in the middle of a big ocean. We know how to settle those on Earth. Yes, I know there's a lot of planetology I'm ignoring here, like the story of ...
The maximum eclipse duration is 72 min out of a 24-hr orbit. These spacecraft tend to be communication satellites and as such are very high powered (1 to 18 AUkW) and the thermal control system needs to remove the heat to keep the transmitters, electronic equipment, and scientific ...
solar system, assemblage consisting of theSun—an averagestarin theMilky Way Galaxy—and those bodies orbiting around it: 8 (formerly 9)planetswith more than 210 known planetarysatellites(moons); manyasteroids, some with their own satellites;cometsand other icy bodies; and vast reaches of highlyte...
9. Earth has 1 Moon and 2 Co-Orbital Satellites: As you’re probably aware, Earth has 1 moon (aka.TheMoon). Plenty is known about this body and we have writtenmany articles about it, so we won’t go into much detail there. But did you know there are 2 additional asteroids locked...
planets and satellites: formationPlanet-planet scattering has been suggested as a mechanism to explain the disproportionate number of planet-planet pairs found to lie on or near an apsidal separatrix, in which one planet's eccentricity periodically drops to near-zero. We present the results of ...
she had already eaten a pomegranate seed. Having fed upon and drank from the goods of the underworld, she was obligated to spend a third of the year with Pluto. Thus, the winter when the Earth is cold and barren is the time Persephone resides in the underworld and Demeter travels the Ea...
Planet Labs PBC operates the PlanetScope constellation of 200 CubeSat (i.e., small, low-cost) satellites (Planet Labs, 2022), imaging a large proportion of the globe every day (Planet Labs, 2018). There have been 3 generations of these PlanetScope “Dove” satellites, improving the radiomet...
the latter having been found by citizen scientists. It may be using WISE data and you may say that doesn't go deep enough but this purported planet is either big enough not to be a tno of any kind or is just another tno and then it will be an happenstance discovery of no real signi...
