# How big is the solar system in miles?

## How big is the solar system in miles?

Our scale model of our Solar System shrinks the distance between the Sun and Pluto to 1 cm from 10 million kilometers….239,000 ÷ 36,373 = 6.57 hours.

Planet Distance from Sun (miles) Distance (cm)
Earth 93 000 000 9.3
Mars 142 000 000 14.2
Asteroid Belt 297 000 000 29.7
Jupiter 484 000 000 48.4

## What are distances in the solar system?

Our solar system is so big it is almost impossible to imagine its size if you use ordinary units like feet or miles. The distance from Earth to the Sun is 93 million miles (149 million kilometers), but the distance to the farthest planet Neptune is nearly 3 billion miles (4.5 billion kilometers).

How many miles is the Milky Way?

600,000 trillion miles
The Milky Way is approximately 100,000 light-years across, or 600,000 trillion miles (950,000 trillion km).

How big is our galaxy in miles?

52,850 light yearsMilky Way / Radius

### How far are the 8 planets from the Sun?

Planet (or Dwarf Planet) Distance from the Sun (Astronomical Units miles km)
Venus 0.723 AU 67.2 million miles 108.2 million km
Earth 1 AU 93 million miles 149.6 million km
Mars 1.524 AU 141.6 million miles 227.9 million km
Jupiter 5.203 AU 483.6 million miles 778.3 million km

### How many miles is Earth’s orbit around the Sun?

92.96 million mi
Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi).

How many suns are in our galaxy?

The Milky Way has a mass of 1.5 trillion suns.

How many galaxies are in space?

All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.

#### How many miles away is the Milky Way?

A little more than four light-years away, or 24 trillion miles as the crow flies. If an airline offered a flight there by jet, it would take 5 million years. Not much is known about this world; its close orbit and the periodic flaring of its star lower its chances of being habitable.

#### How far away is a light year?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).

How far does our solar system travel in one orbit?

Our sun and solar system move at about about 500,000 miles an hour (800,000 km/hr) in this huge orbit. So in 90 seconds, for example, we all move some 12,500 miles (20,000 km) in orbit around the galaxy’s center. Our Milky Way galaxy is a big place.

How many miles does the Earth travel a day?

1.6 million miles
Per day, we travel 1.6 million miles. This is farther than the distance that most people drive motor vehicles in a lifetime. (The average car in America is driven about 12,000 miles per year.) We can find the Earth’s orbital speed by dividing 1.6 million miles by 24 hours, yielding 66,700 miles per hour.

## Can a planet have two suns?

Can a planet really have two suns? While many things about Star Wars are purely fictional, it turns out that planets orbiting two or more stars is not one of them. In 2011, NASA embarked on the Kepler mission, exploring the Milky Way galaxy to find other habitable planets.
