Scale of the Universe is a visual tool for getting a sense of the scale of various objects in the universe. It has a wide collection of objects ranging from the smallest subatomic particles to the largest galaxies.
The Observable Universe is estimated to be about 93 billion light-years in diameter. That’s a lot of light-years! To give you a better idea, if you were to drive a car at a speed of 60 miles per hour, it would take you about 200 trillion years to drive across the Observable Universe.
Scientists have been trying to measure the size of the universe for centuries. And while the exact size is still a mystery, we have a pretty good idea about the size of the observable universe - the part of the universe we can see from Earth.
The Earth is the fifth largest planet in our Solar System. It’s smaller than the gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune. But, it’s larger than Mars, Venus, and Mercury, and dwarf planets like Pluto. If the Sun was a door, Earth would be a nickel in comparison.
Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale.

Named after a brilliant German physicist named Max Planck, who proposed this concept in 1899, the Planck Length is so incredibly tiny that it’s almost impossible to imagine. To give you an idea, it’s about 10^-35 meters. That’s a decimal point followed by 34 zeroes and then a 1!
Have you ever wondered what the smallest thing in the universe might be? No, it’s not an ant, or even a speck of dust. It’s something so tiny, so minuscule, that it’s almost impossible to imagine. It’s called quantum foam.
