Full Answer

There will never be what is called an "exact" planetary alignment because of the different orbits of the planets. It is estimated that there will be another close alignment, meaning about 30 degrees within each other, of all eight planets in 2438, similar to the one that occurred in 1962. Beyond that, it could take millions of years before all eight of the planets ever align in perfect harmony again.

  • Q:

    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.

    How are planets and dwarf planets similar?

    A:

    As of 2015, scientists define dwarf planets as bodies that are similar to planets in that they orbit a star, are large enough to form a round shape and are not moons. However, dwarf planets do not have sufficient gravity to push away other bodies that might intersect their orbits.
