## What are the objects in space from smallest to largest?

From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.

How big is the size of space?

The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m). Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22×104 Gpc3 (4.22×105 Gly3 or 3.57×1080 m3).

### How small is a person compared to the universe?

The size of an average human is 176.5 cm or 1.76 m while the diameter of the solar system alone is 287.46×1011m. Therefore, the solar system is about 163.33×1011 times greater than a human then the universe must be infinite times greater than a human.

How big the Earth is compared to the universe?

The Solar System is about 36 billion times larger than Earth (3.6 X 10^10).

## What is the largest body in the Universe?

The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!

Which is bigger Pluto or the moon?

Pluto is smaller than Earth’s moon. Its largest moon is named Charon (KAIR-ən). Charon is about half the size of Pluto. Pluto’s four other moons are named Kerberos, Styx, Nix and Hydra.

### What is the biggest thing in space?

Hercules-Corona Borealis Great Wall
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!

Why is space so big?

Why is the Universe so Big? The Universe is so big because it is constantly expanding, and it does so at a speed that even exceeds the speed of light. Space itself is actually growing, and this is going on for around 14 billion years or so.

## How much bigger are humans to ants?

Insect Scale A human is about 750 times taller than an ant. Note, don’t confuse this with mass or volume. A human is way more than 750 times the volume of an ant.

How big is a big human?

Given these further limitations, I would guesstimate that the largest feasible scale for a human will be at most x4, for a height of 7m20cm, with a mass of 5.120 kg. With a slightly more squat build, call it 7m and 5 tons. I’d say the minimum height for the largest human might be 9 feet.

### How many Earths are in the universe?

Throughout the universe, trapped in the halos of dark matter, there is enough planet-making material to create at least 1,000,000,000,000,000,000,000 more Earth-like planets. A billion trillion of them.

Does the universe end?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
