It is not exactly a sphere, the longest axis is 15km and the shortest one is 8km.
Meteoroids are smaller than both comets and asteroids. They are small rocky or metallic objects that are typically smaller than asteroids and comets, which are large bodies that can range in size from several meters to hundreds of kilometers in diameter.
Asteroids are generally bigger than comets, with sizes ranging from a few meters to hundreds of kilometers in diameter. Comets are typically smaller and are made up of rock, dust, and ice. However, there can be exceptions, and sizes can vary among individual asteroids and comets.
Hale-Bopp comet had a nucleus estimated to be about 18 to 40 kilometers in diameter, making it one of the largest observed comets of the 20th century.
Usually, a comet.Meteors are usually the dust trails of comets or bigger meteorites/asteroids that burn up in the Earth's atmosphere. They are about the size of grains of sand.
They are all less than a kilometer in diameter.
i do not know :D
comets
They range from a diameter of 100m to 40+ kilometers
Comets are generally fairly large, dozens or hundreds of miles in diameter. Small compared to planets or asteroids, but large compared to meteors or dust.
Although comets appear very large when they are near the Sun because of the large dust cloud that follows behind them, they are actually the smallest of the objects listed. Comets typically have a diameter of less than 6 miles, which is much smaller than the typical diameter of the other objects listed above.
Meteoroids are smaller than both comets and asteroids. They are small rocky or metallic objects that are typically smaller than asteroids and comets, which are large bodies that can range in size from several meters to hundreds of kilometers in diameter.
No, comets are generally much smaller than planets. Comets are composed of ice, dust, and rocky materials and can range in size from a few hundred meters to tens of kilometers in diameter. In comparison, planets are much larger celestial bodies that orbit stars and have a defined spherical shape.
Asteroids are generally bigger than comets, with sizes ranging from a few meters to hundreds of kilometers in diameter. Comets are typically smaller and are made up of rock, dust, and ice. However, there can be exceptions, and sizes can vary among individual asteroids and comets.

The singular form is comet, the plural form is comets, the possessive plural is comets'. Example: The comets' paths will not cross.
