SOLAR SYSTEM

Detailed explanation-1: -Occurance of comets is a natural phenomenon and there is nothing superstitious about it. Many comets appear after fixed time interval for example, Halley"s comet which appears once in every 76 years.

Detailed explanation-2: -When a comet moves on it’s orbit close enough to the Sun, ice and other volatile matter starts to evaporate, making them easier to see, sometimes even with a naked eye. As the comet gets away, this process stops-until the comet completes a full revolution and is back.

Detailed explanation-3: -A statement is true if what it asserts is the case, and it is false if what it asserts is not the case. For instance, the statement “The trains are always late” is only true if what it describes is the case, i.e., if it is actually the case that the trains are always late.

Detailed explanation-4: -Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.

Detailed explanation-5: -A comet is a ball of mostly ice that moves around in outer space. Comets are often described as “dirty snowballs". They are very different from asteroids. The orbital inclinations of comets are usually high and not near the ecliptic where most solar system objects are found.

Detailed explanation-6: -We can see a number of comets with the naked eye when they pass close to the sun because their comas and tails reflect sunlight or even glow because of the energy they absorb from the sun. However, most comets are too small or too faint to be seen without a telescope.
