Concept explainers
The rank in the order of smallest to largest.
Answer to Problem 1QP
The rank in the order of smallest to largest is
Explanation of Solution
Earth revolves around the Sun, and the diameter of sun is about 109 times greater than the diameter of Earth.
Solar System is the gravitationally bound system which consists of Sun, Earth and other bodies.
Milky Way galaxy is the galaxy in which the solar system reside.
Local Group is the group of few dozen galaxies like Milky Way galaxy.
Virgo Supercluster is the group of thousands of galaxies.
Laniakea Supercluster is the even larger grouping of galaxies than Virgo supercluster.
Universe is the all of space and time that exist.
Conclusion:
The rank in the order of smallest to largest is Earth<Sun<Solar system<Milky way<local group<milkyway<virgo supercluster< Laniakea Supercluster<Universe.
The rank in the order of smallest to largest is
