The best known among these structures is the primary rainbow, which appears in sunlit raindrops as a colored circular segment of radius 42[degrees], centered on one's shadow point (also called the
antisolar point).
nuclear diameter: 1-40 km (Halley:16 x 8 x 7 km) nuclear mass: 1014-1019g (Halley: 1017-1018g) nuclear mass loss per apparition: ~1 % coma radius: 104-105 km hydrogen cloud radius: 107 km dust tail length: 106-107 km dust tail particle size: 0.1-100 microns dust tail direction:
antisolar, becoming curved as dust particles follow independent orbits ion tail length: 106-108 km ion tail direction:
antisolar short-period comets: period < 200 years long-period comets: period > 200 years comet discovery rate: ~12 per year number of comets discovered to date: ~4 000 average number of apparitions per year: ~17
The ZnO nanoparticles are used in
antisolar creams, pigments, electricity cables, tiles and etc [1].
But solar sailing, on the contrary, is a continuous process and the mathematics for reaching final conditions is far more complex, even more than in the case of electric propulsion, since the thrust intensity is related to the sail orientation: the orientation of the force vector applying to a perfectly reflective solar sail is normal to the sail, in the
antisolar direction.
The position of the point diametrically opposite the Sun along the ecliptic--the
antisolar point--should also be noted, by looking at the point on the opposite side of the back of the mother.
There are also some literature reports on
antisolar, antidepressant, hypnotic, CNS depressant and antitussive effects of this plant (Rakhshandah et al.
The far brighter, inner coma measured a bit more than 11' across, and to the south (in the
antisolar direction) it looked faded and shredded.
Cometary dust is pushed in the
antisolar direction by the Sun's radiation pressure.
