Comets always have two tails (ion tail and dust tail) and are so seen that way. the one tail (ion tail) is always pointing away from the sun showing which direction the comet is in comparison to the sun. the sun gives off a charge and hits the comet and that moves the ion tail showing which way the sun is. the (dust …

WebStructure in the ion tail comes from different rates of expelled blue-glowing ions from the comet's nucleus, as well as the always complex and continually changing structure of … WebMar 31, 2024 · When astronomers look closely, they find that comets actually have two separate tails. One looks white and is made of dust. This dust tail traces a broad, gently curving path behind the comet. The other tail is bluish and is made up of electrically charged gas molecules, or ions. The ion tail always points directly away from the Sun. lil wayne accomplishments

Since it … http://burro.astr.cwru.edu/Academics/Astr221/SolarSys/Comets/tails.html The tail of dust is left behind in the comet's orbit in such a manner that it often forms a curved tail called the antitail, only when it seems that it is directed towards the Sun. At the same time, the ion tail, made of gases, always points along the streamlines of the solar wind as it is strongly affected by the … See more A comet tail—and coma—are features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the … See more While the solid nucleus of comets is generally less than 30 km across, the coma may be larger than the Sun, and ion tails have been observed to extend 3.8 astronomical units See more If the ion tail loading is sufficient, then the magnetic field lines are squeezed together to the point where, at some distance along the ion tail, magnetic reconnection occurs.
