Which of the following space objects is the largest in size?
Jupiter
The Sun
The Milky Way
an asteroid
Explanation
The answer is "The Milky Way." Distances in the universe are so vast that they can be difficult to comprehend. We measure distances in space using light years. A light year is about 6 trillion miles, the distance light travels in one Earth year.
We live on Earth, a planet in a solar system that orbits our sun. Our solar system is only part of a much larger system of many billions of stars called the Milky Way Galaxy. The Milky Way is shaped like a disk with concentrations of brighter stars and clouds of gas shaped like a whirlpool. The Milky Way is only one galaxy of many billions of galaxies in the universe.
In order from smallest to largest, some important terms to remember are: planets and stars, solar systems, galaxies, the universe. Each term is a component of the next. (Aside from planets and stars which are both different components of solar systems.)
In comparison to our solar system, the Milky Way Galaxy is:
older and larger
the same age and larger
younger and larger
younger and smaller
Explanation
The answer is "older and larger."

As time moved forward after the big bang, the universe expanded, resulting in the collision of particles of matter and the creation of celestial objects. Which of the celestial objects listed in the answer choices were formed last?
spiral galaxies
stars
planets
solar systems
Explanation
The answer is "spiral galaxies" because stars, planets, and solar systems are required for their formation.
