A comet is a lump of rock and ice. Spacecraft have flown by comets. A comet only has a tail when it is near the sun. Most comets come from the Kuiper belt. A comet has actually been witnessed hitting a planet. Most comets have short orbital periods.
A comet is a tiny, frozen entity in the Solar System that heats up and starts to emit gases as it approaches the Sun. This process is known as outgassing. This results in an apparent atmosphere or coma, and occasionally a tail as well. These occurrences are caused by how the solar wind and solar radiation interact with the comet's nucleus.
The size of comet nuclei varies between a few hundred meters and tens of kilometers, and they are made up of loose clumps of ice, dust, and tiny rocky particles. A comet's orbit is typically very eccentric and elliptical, and its orbital period can range from a few years to possibly millions of years.

Water plays an important role in weathering and breaking down rock. ... Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth's surface.
The eight-digit grid coordinate gives exactness to the nearest 10 meters. Read below about the grid coordinate of the above given map.
<h3>What are the eight-digit grid coordinates for benchmark 86 (circled in red)? </h3>
Grid coordinates are said to be correctly target to a definite area, using a map that starts with upright and straight lines of same spacing and signals connected to every line to define out a destination.
The traverse vertical and horizontal lines have different figures and make little squares defined as grid squares. The more digits in the coordinate of a boundary, the improvement in precision an eight-digit provides a accuracy to the nearest 10 meters.
Therefore, the correct answer is as given above.
