Right now, on March 20, 2011? There is none. The frozen core of Halley's Comet is drifting away from the Sun, and is out past the orbit of Neptune and slowing down. In about 10 years, Halley's Comet will reach aphelion (the farthest point in its orbit) and slowly begin to fall back inward. The comet probably won't develop any kind of tail until it gets in about to the orbit of Jupiter; that will be around 2055 or so.
it is the time when the tail is facing the north of the other comets like this <halleys tail is north of the other comets when they go > this way
Comets!
Celestial comets is a more formal name for comets. Comets are objects in space orbiting the Sun with long orbits. They are thought to be made of frozen water. As they near the Sun they produce a long glowing tail trailing behind.
A star with a long tail is typically referred to as a comet. Comets are icy bodies that release gas and dust as they approach the Sun, forming a glowing coma and a tail that points away from the Sun due to solar wind and radiation pressure. The tail can appear quite elongated and is one of the most distinctive features of comets.
Comets are made of mainly 3 parts -dust tail, ion tail and coma
Comets
A Comets tail points away from the sun.
The mass of material with a long tail that travels around the sun is called a comet. Comets are composed of ice, dust, and small rocky particles. The tail of a comet is formed when it gets closer to the sun, and the heat causes the ice to vaporize and create a glowing tail. The mass of a comet can range from a few million kilograms to billions of kilograms.
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
