What is the distance across our solar system
Planetary Systems
Our solar system began to form about 4.6 billion years ago. Astronomers think small rocky and icy grains within the solar nebula began sticking together, growing into even larger objects. Although the process remains poorly understood, solid objects miles or more across eventually populated the disk. Astronomers call these bodies planetesimals.
Temperatures Across Our Solar System
As we keep moving out into the solar system, we come to Saturn – the sixth planet from the Sun and the second largest planet in our solar system. Saturn orbits the Sun from an average distance of 886 million miles (1.4 billion kilometers). It takes sunlight 80 minutes to travel from the Sun to Saturn.
Jupiter Facts
Jupiter is the largest planet in our solar system. Jupiter''s iconic Great Red Spot is a giant storm bigger than Earth. From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun.
Our Milky Way Galaxy: How Big is Space?
A trip at light speed to the very edge of our solar system – the farthest reaches of the Oort Cloud, a collection of dormant comets way, way out there – would take about 1.87 years. Keep going to Proxima Centauri, our nearest neighboring star, and plan on arriving in
Chapter 1: The Solar System
The solar system consists of an average star we call the Sun, its "bubble" the heliosphere, which is made of the particles and magnetic field emanating from the Sun - the interplanetary medium - and objects that orbit the Sun: from as close as the planet Mercury all the way out to comets almost a light-year away.A light year is the distance light travels in a year, moving at about
18.1: Introduction to the Solar System
Today, we know that our solar system is just one tiny part of the universe as a whole. Neither Earth nor the Sun are at the center of the universe. However, the heliocentric model accurately describes the solar system. In our modern view of the solar system, the Sun is at the center, with the planets moving in elliptical orbits around the Sun.
Distances of the Planets From the Sun in Light Years
It can be difficult to grasp just how enormous the solar system is. At the heart of that system is the sun, the star around which all the planets orbit. The result was the light year, which covers the distance that light travels in one year. That distance is nearly 6 trillion miles, but a light year conveys time more than it does actual

Size and Distance. Size and Distance. Our Sun is a medium-sized star with a radius of about 435,000 miles (700,000 kilometers). Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330,000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun''s volume
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 Big Is The Solar System?
The heliopause is perhaps the most accepted definition of where the solar system ends. If we define the end of the solar system as the heliopause, our solar system averages at 11 billion miles (18 billion kilometres) from the sun to the heliopause. However, one issue with this definition is that the heliopause is constantly fluctuating.

The Outer Reaches of the Solar System. There are objects belonging to our Solar System that are even farther than the orbit of our planets. The Kuiper Belt is a disk-shaped region past the orbit of Neptune, roughly 4,400,000,000 to 14,900,000,000 km (30 to 100 AU) from the Sun, that consists mainly of small bodies which are the remnants from
Size of the Solar System
What is the distance from the Earth to the Sun? 93 million miles. Although we think our planet is very large, when we compare it to other objects in our solar system, it is really quite small. We could fit 1000 Earths inside Jupiter. Everything is scaled, so the Sun is only 1 and 1/2 feet across, and Pluto is the size of a pin head.
In Depth | Our Solar System – NASA Solar System Exploration
Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

Cosmic Distances
Astronomical units, abbreviated AU, are a useful unit of measure within our solar system. One AU is the distance from the Sun to Earth''s orbit, which is about 93 million miles (150 million kilometers). When measured in astronomical units, the 886,000,000-mile (1,400,000,000-kilometer) distance from the Sun to Saturn''s orbit, is a much more

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.

6 FAQs about [What is the distance across our solar system]
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).
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.
How do astronomers measure the distance between Earth and Sun?
Astronomers use the distance between Earth and sun, which is 93 million miles, as a new unit of measure called the Astronomical Unit. It is defined to be exactly 1.00 for the Earth-Sun orbit distance, and we call this distance 1.00 AUs. Problem 1 - The table below gives the distance from the Sun of the eight planets in our solar system.
How do astronomers measure the size of 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.
How do we calculate the distance between planets?
For this reason, to calculate the distance, we use the average to measure how far planets are from one another. The Astronomical units (AU) column is the average distance between Earth and the Sun and is the most common way for scientists to measure distance in our Solar System.
How long does it take to reach the edge of the Solar System?
At those distances, it would take you 19 million years to complete the journey to the edge of the Solar System. Even NASA’s New Horizons spacecraft, the fastest object ever launched from Earth would need 37,000 years to make the trip. So as you can see, our Solar System is a really really big place.
