The universe is a vast and mysterious place. It is so large that it is impossible to comprehend its true size. The diameter of the observable universe is estimated to be about 93 billion light-years. That's a distance so great that it would take light about 93 billion years to travel from one end of the universe to the other.
To put this into perspective, the distance from Earth to the Sun is about 93 million miles. The distance from Earth to the nearest star, Proxima Centauri, is about 4.2 light-years. The diameter of our galaxy, the Milky Way, is about 100,000 light-years.
The universe is home to an estimated 2 trillion galaxies, each containing billions or trillions of stars. The smallest stars are about the size of Jupiter, while the largest stars are so big that they could fit millions of Earths inside of them.
Planet Size Comparison
The planets in our solar system range in size from Mercury, which is only about the size of our Moon, to Jupiter, which is so big that it could fit over 1,300 Earths inside of it.
