Bursts of Jovian electrons in the energy range 330 MeV have been detected to distances of the order of 1 AU from the planet. The duration of each burst was about 23 days, and the maximum intensity increased with increasing distance from the sun. These events could not be correlated with ...
(AU) to more than 100 AU), with the smallterrestrial planetsgrouped near the Sun, the giant planets grouped outside, and several populations of small bodies distributed throughout this range of distances; (2) the diversity of its secondary systems, with their host of regular satellites ...
As H I atoms absorb the Lyα photons coming from the Sun, the solar radiation is blocked during the transit of the planet in front of the star. Despite the difficulty of mapping this region through Lyα measurements from distances far from the Earth’s surface, and the problematic presence...
Model the solar system with distances from everyday life to better comprehend distances in spaceThe solar system[1] consists of the Sun and many smaller objects: the planets, their moons and rings, and such “debris” as asteroids, comets, and dust. Decades of observation and spacecraft explo...
In 1619,Keplerdiscovered a basic relationship to relate the planets’ orbits to their relative distances from the Sun. We define a planet’sorbital period, (P), as the time it takes a planet to travel once around the Sun. Also, recall that a planet’s semimajor axis,a,is equal to its...
In the frame of the “Effect of Megacities on the transport and transformation of pollutants on the regional to global scales” (EMeRGe) project, ATDM forecasts were carried out to identify potential airborne sampling areas of perfluorocarbons (PFCs) emanating from controlled PFC releases. The ...
The large distances between Earth and other solar system objects preclude global observations of high spatial resolution, except from spacecraft that fly by the objects or that are placed in orbits around them (Fig. 4). As noted in Section II.A, in situ observations require landers or rovers...
the distances of periapse (closest point to the central body) and apoapse (furthest point). The other orbital elements include angles that rotate the orbits around the Cartesian axes and a time of periapse. If the units on the axes are taken to be AU, the orbits shown are Earth-like ...
9. However, CH4-rich atmospheres in the HZ may not be possible without life to generate substantial CH4(refs.10,11). In addition, more complex climate models have shown the HZ might extend to smaller orbital distances, perhaps interior to Venus’ orbit, with appropriate planetary conditions12,...
Superrotation is a dynamical regime where the atmosphere circulates around the planet in the direction of planetary rotation with excess angular momentum in the equatorial region. Superrotation is known to exist in the atmospheres of Venus, Titan, Jupiter, and Saturn in the solar system. Some of...
