This illustration shows the approximate sizes of the planets relative to each other. Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, followed by the dwarf planet Pluto. Jupiter''s diameter is about 11 times that of the Earth''s and the Sun''s diameter is about 10 times Jupiter''s.

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.
Mercury – The smallest planet in our solar system, Mercury''s radius is about 2,440 km (1,516 mi), making its diameter roughly 4,880 km (3,032 mi). It is about 0.38 times the size of Earth.

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. Our solar system is moving with an
Each planet in our solar system possesses a distinct diameter, which is a measure of its size or width. For instance, Jupiter, the largest planet, boasts a diameter of approximately 86,881 miles (139,820 kilometers). Saturn follows closely behind with a diameter of around 72,367 miles (116,464 kilometers).
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.
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. Jupiter''s diameter is about equal to the thickness of a U.S quarter in our shrunken solar system.
How Big Is The Solar System? The size of the solar system may seem like it has a simple answer, yet there is no universally agreed upon definition for where our solar system ends. There are three possible definitions for where our solar system ends: the heliopause, the edge of the Oort Cloud, and the gravitational influence of the sun.How big is our solar system
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
The most giant planet in our Solar System, namely Jupiter, has a diameter of around 142.984 km / 88.846 mi at the equator, and a diameter of about 133.708 km / 83.082 mi at the poles. It has a mean radius of 69.911 km / 43.440 mi, and its
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.

Introduction to the Solar System. A: What is the Solar System? Since the Sun is 696,000 km in radius, its diameter in miles is about 860,000 miles. Let us choose 1" = 100,000 miles, so that our Sun will be about 8.6 inches in diameter.
Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun.The solar radius is usually defined as the radius to the layer in the Sun''s photosphere where the optical depth equals 2/3: [1] = 695,700 kilometres (432,300 miles) is approximately 10 times the average radius of Jupiter, 109 times the radius of the Earth, and 1/215th of an
4 · With an equatorial radius of 6,378 km (3,963 miles), Earth is the largest of the four inner, terrestrial (rocky) planets, but it is considerably smaller than the gas giants of the outer solar system.Earth has a single natural satellite, the Moon, which orbits the planet at a mean distance of about 384,400 km (238,900 miles).The Moon is one of the bigger natural satellites in the

The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light
Jupiter is the largest planet in our solar system. Jupiter''s iconic Great Red Spot is a giant storm bigger than Earth. With a radius of 43,440.7 miles (69,911 kilometers), Jupiter is 11 times wider than Earth. If Earth were the size of a grape, Jupiter would be about as big as a basketball.
By this definition, the radius of the solar system could be 937 AU in any direction from the Sun, so 1,874 AU in total diameter. Regardless of which scale you use, the solar system is massive. with a mass of about 1.989 x 10 30 kg and a radius of 696,340 km. In terms of mass, the Sun is about 333,000 times the mass of Earth. In terms of
