Full Answer

Speaking of planetary alignment, the term should not be taken to mean that the planets will line up perfectly. That is an occurrence that can never happen due to the unique orbits of the planets. Scientists typically refer to alignment as being the instance where the orbits of the heavenly orbs are all within 30 degrees of each other. When there is a perfect alignment, usually only two or three planets make it to the party.

    Why are planets round?

    A:

    According to NASA, gravity is the reason why planets are round. Gravity causes any matter to attract toward any other matter. When planets began to form, the earth’s solar system was one big swirling disk that contained dust and gas, with the sun at its center. Particles of dust and gas pulled toward each other due to gravity.
