A short-period comet is a comet that has a relatively short lifespan for any observation can be made for comparative studies. That period is known to be shorter than two hundred years. Recently, short-period comets have been subdivided into the Jupiter-type comets, like that of Temple 2 and Encke, which typically have periods of just twenty years; and the Halley-type comets, with intermediate periods of between twenty to about two hundred years.

Comets are spectacular sights in the night sky. Despite their burning appearance, comets are actually made of ice, small rock particles, and dust. But comets, unlike meteors, are rarely seen in the night sky. Comets have different orbital periods, which can range from several years to hundreds of thousand years. Comets are classified according to the range of their orbital periods, namely long and short period comets. Short period comets are collectively known as periodic comets with orbital periods of [...]

The Oort cloud is an enormous spherical cloud composed of comets and dust. Its size is hypothesized to be at 2000 or 5000 to 50,000 astronomical units (AU)-an AU equals the distance between the earth and sun. The sphere is so huge that its border is closer to the Earth’s nearest star as opposed to the sun itself. The spherical shape of the Oort cloud
