See how large the planets appear in the sky. For local times and where to look etc., try the night sky in your location. The planets' apparent size is measured in arcseconds ("). For comparison, the Sun and the Moon measure about 1800 arcseconds.
We measure the apparent brightness of celestial bodies in magnitude. The brighter a planet shines, the lower the magnitude value. Negative numbers indicate that the planet is very easy to spot in the night sky, even with ambient light. The planets' distance from the Sun varies because all the planets orbit the Sun on different elliptical paths. The top row of planets shows the distance in kilometers or miles. The second row of planets dotted on a line illustrates their relative distance from the Sun and each other.

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
5 · The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main
The planet follows the ellipse in its orbit, meaning that the planet-to-Sun distance is constantly changing as the planet goes around its orbit. Kepler''s Second Law: The imaginary line joining a planet and the Sun sweeps out – or covers – equal areas of space during equal time intervals as the planet orbits. Basically, the planets do not
Planetary Systems Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock. This protoplanetary disk may extend more than 100 times Earth''s distance from the Sun.

With a radius of 3,959 miles (6,371 kilometers), Earth is the biggest of the terrestrial planets and the fifth largest planet overall. From an average distance of 93 million miles (150 million kilometers), Earth is exactly one astronomical unit away from the Sun because one astronomical unit (abbreviated as AU), is the distance from the Sun to
The last planet in the inner solar system is Mars. Orbiting between 127-million miles and 155-million miles, Mars has an average distance of 142-million miles from the sun. At 1.52 AU, Mars is 1.5 times further from the sun than the Earth is. Outer Solar System The four gas giants of the outer solar system. Image credit: NASA
Each planet''s width is compared to Earth''s equatorial diameter, which is about 7,926 miles (12,756 kilometers). At the bottom of the page, there is a handy list of the order of the planets moving away from our Sun. Jupiter is the largest planet in the solar system.
The table below (first created by Universe Today founder Fraser Cain in 2008) shows all the planets and their distance to the Sun, as well as how close these planets get to Earth. Mercury: Closest
High precision ephemerides for the planets are available via the Horizons system. Accuracy. The table below lists nominal errors in heliocentric longitude, λ, latitude, φ, and distance, ρ, using this approximation of planetary positions.
Mercury is the first planet in our solar system. It is the closest planet to the Sun, located at an average distance of 36 million miles (58 million kilometres) from our star cause this small planet is so close to the Sun''s harmful solar winds, it
Earth is a big place. If you could drive around the entire planet, it would take more than sixteen days of non-stop driving at highway speeds. But, compared to some of the planets in our solar system, it''s
This artist''s concept puts solar system distances in perspective. The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is
4 · Earth - Planet, Atmosphere, Geology: The mean distance of Earth from the Sun is about 149,600,000 km (92,960,000 miles). The planet orbits the Sun in a path that is presently more nearly a circle (less eccentric) than are the orbits of all but two of the other planets, Venus and Neptune. Earth makes one revolution, or one complete orbit of the Sun, in about 365.25
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.
Earth is the fifth largest planet in the solar system. It has an equatorial diameter of about 7,926 miles (12,756 kilometers). Earth is the third planet from the Sun, orbiting at an average distance of 93 million miles (149.7
Our solar system includes the Sun, eight planets, five dwarf planets, and hundreds of moons, asteroids, and comets. is the distance from the Sun to Earth, or about 93 million miles (150 million kilometers). The Oort Cloud is the boundary of the Sun''s gravitational influence, where orbiting objects can turn around and return closer to our Sun.
The distance among each of the eight planets in our Solar System will alter depending on where each planet is in its orbit revolution around the Sun. Depending on the time of year the distance can also differ significantly. The main reason for the planets to vary their distance is due to elliptical orbits.
Kepler''s third law implies that the greater the distance of a planet from the Sun, the longer the period of that planet''s orbit around the Sun. Thus, Mercury — the planet closest to the Sun — makes an orbit every 88 days. By contrast, Saturn, the sixth planet in the solar system from the Sun, will take as many as 10,759 days to do so.
The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] To-scale diagram of distance between planets, with the white bar showing orbital variations. The size of the planets is not to scale.
Half this distance—that is, the distance from the center of the ellipse to one end—is the semimajor axis, which is usually used to specify the size of the ellipse. For example, the semimajor axis of the orbit of Mars, which is also the planet''s average distance from the Sun, is 228 million kilometers. Figure 3.4 : Drawing an Ellipse.
The small planet has a diameter of 4.879 km / 3.032 mi. Venus. The second closest planet to the Sun. Venus is on average at a distance of 108 million km / 67 million mi or 0.72 AU away from the Sun. It is the hottest planet of the Solar system since its atmosphere keeps the temperatures almost consistently the same.
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
Learn about sizes and distances in our solar system. Distances in the solar system can be huge! The distance from the Sun to Neptune is nearly three billion miles (four billion kilometers). Because the distances between planets are so great, astronomers sometimes describe distances in terms of astronomical units (AU). One AU is equal to the
Our Solar System''s Planets in Order. Our solar system revolves around the sun, hence the name solar system. In our system, we have 4 terrestrial planets, 4 gas giants, and a mysterious 9th planet.

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
The Titius–Bode law (sometimes termed simply Bode''s law) is a formulaic prediction of spacing between planets in any given planetary system.The formula suggests that, extending outward, each planet should be approximately twice as far from the Sun as the one before. The hypothesis correctly anticipated the orbits of Ceres (in the asteroid belt) and Uranus, but failed as a
Half this distance—that is, the distance from the center of the ellipse to one end—is the semimajor axis, which is usually used to specify the size of the ellipse. For example, the semimajor axis of the orbit of Mars, which is also the planet''s average distance from the Sun, is 228 million kilometers.
