Yesterday I commented on comets and I did not complete it so I will add and in reference to the image of the day that these are bodies of agglomeration of planetesimals in some area to the protection of the T-Tauri phase of the Sun in what today is known as the Oort cloud (more accurately Oort-Opik), composed mostly of water and fine dust with some larger rocks that can be as big as mountains, when it approaches the focus of its orbit (the Sun) and is about 5-9 AU away, not infrared heat but UV radiation heats it and small material such as water molecules or dust grains of 10-10,000 atoms become excited and begin to break down into steam or dust currents that are blown by the wind solar is driven in the opposite direction to the Sun generating the tails of dust and ions or plasma.
Kites with up to seven caudae have been seen (16th century) and as long as 10 AU. In order to maintain the movement, these "tails" take the same orbit of the nucleus throughout the entire trajectory and when the Earth's orbit (or any of the other objects with sufficient gravitational power) passes through it, "rain showers stars "that are nothing more than the remnants of dust from these" tails ", the brightest, are generally the size of a grain of sand and the rest one hundredth or thousandth smaller, the giants are called bolides.
