How far across is our solar system

Jupiter

Jupiter is the fifth planet from the Sun and the largest in the Solar System is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is eleven times that of Earth, and a tenth that of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital

Imagine the Universe!

The Milky Way is approximately 100,000 light-years in diameter. Our solar system is 26,000 light-years from the center of the Galaxy. All objects in the Galaxy revolve around the Galaxy''s center. It takes 250 million years for our Sun (and the Earth with it) to make one revolution around the center of the Milky Way.

In Depth | Neptune – NASA Solar System Exploration

Dark, cold, and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system. More than 30 times as far from the Sun as Earth, Neptune is the only planet in our solar system not visible to the naked eye. These winds whip clouds of frozen methane across the planet at speeds of more than 1,200 miles

How Big is Our Solar System?

The best way to appreciate the size of our solar system is by creating a scaled model of it that shows how far from the sun the eight planets are located. Astronomers use the distance between Earth and sun, which is 93 million miles, as a new unit of measure called the Astronomical Unit. It

How far across is the Milky Way?

As far as we can tell, the Sun and the solar system are not moving away from the center of the galaxy. The Sun has made less than 25 trips around the galaxy in its lifetime. The center of our galaxy is located about 28,000 light-years away, beyond the constellation Sagittarius (actually just beyond the border of Sagittarius and Scorpio ).

Cosmic Distances

Astronomical units are a useful measure for distances in our solar system, while light years are more practical for distances to the stars. (9 trillion kilometers, or 63,000 AU). Put another way, a light year is how far you''d travel in a year if you could travel at the speed of light, which is 186,000 miles (300,000 kilometers) per second.

How did scientists determine our location within the Milky Way

The essential modern picture is that our solar system is located on the inner edge of a spiral arm, about 25,000 light-years from the center of the galaxy, which is in the direction of the

How far does our Solar System extend?

Our Solar System extends much, much farther than where the planets are. The furthest dwarf planet, Eris, orbits within just a fraction of the larger Solar System. The Kuiper Belt, where we find a Pluto, Eris, Makemake and Haumea, extends from 30 astronomical units all the way out to 50 AU, or 7.5 billion kilometers. And we''re just getting started.

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

How fast are we traveling through space?

The Earth orbits the Sun at roughly 107,000 kilometers per hour. Our Solar System rotates around the Milky Way galaxy at approximately 700,000 kilometers per hour. Additionally, the galaxy travels at an immense speed away from every other galaxy as the universe continues to expand, with vastly differing relative speeds depending on the

The 5 hours it takes light to travel across our Solar System may seem like a short period to cross such a large distance, but we have to think about scale. While distances within the Solar System are large to us, they are dwarfed by the

How many astronomical units is 93 million miles from the Sun?

The Earth averages at 93 million miles (150 million kilometres) from the sun, and so one astronomical unit is equal to that number. Visualization of the solar system from the sun to the Oort Cloud. NASA Another definition for where the solar system ends is the edge of the Oort Cloud.

The mosaic shows the entire Valles Marineris canyon system stretching across the center of Mars. It''s more than 2,000 miles (3,000 kilometers) long, 370 miles (600 kilometers) wide and 5 miles (8 kilometers) deep. Pluto is the largest dwarf planet in our solar system, just slightly larger than Eris, at number two. Pluto has an equatorial

Neptune Facts

Neptune is our solar system''s windiest world. Despite its great distance and low energy input from the Sun, Neptune''s winds can be three times stronger than Jupiter''s and nine times stronger than Earth''s. These winds whip clouds of frozen methane across the planet at speeds of more than 1,200 miles per hour (2,000 kilometers per hour).

How long to orbit Milky Way''s center?

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

How Big is Our Solar System? 1

How Big is Our 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). Compare

How far away is Jupiter from the Sun?

Jupiter remains pretty close to our end zone on the 10.5-yard line. Our solar system''s largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun. That''s 5.2 AU. Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale.

How Far Is Each Planet?
