Mercury and Venus Mercury is the closest planet to the sun, at an average distance of 36 million miles. Venus is next in line, at 67.1 million miles. Subtracting 36 from 67.1 equals 31.1, meaning that the distance between Mercury and Venus is 31.1 million miles.

The equatorial diameter Earth is about 7926 miles (12,756 km) while the polar diameter is 7900 miles (12,714 km). The equatorial circumference is approximately 24,900 miles (40,075 km). The equatorial bulge is due to the centrifugal force exerted on the Earth by its rotation.

Mercury is a rocky planet with a huge iron core which makes up a large part of its interior. The core takes up nearly 3/4 of the planet's diameter. Mercury's iron core is about the size of the moon. Iron makes up about 70% of Mercury's total weight making Mercury the most iron-rich planet in the Solar System.

Earth's moon is the fifth largest moon in the solar system. The moon's mean radius is 1,079.6 miles (1,737.5 kilometers). Double those figures to get its diameter: 2,159.2 miles (3,475 km), less than a third the width of Earth. The moon's equatorial circumference is 6,783.5 miles (10,917 km).

Size and Distance If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.

With a radius of 3,760 miles (6,052 kilometers), Venus is roughly the same size as Earth — just slightly smaller. From an average distance of 67 million miles (108 million kilometers), Venus is 0.7 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.

The mean diameter of Jupiter is 138,346.5 km, the equatorial diameter being 142,984 km and the polar diameter being 133,709 km. The average diameter of the Earth is 12,742 km meaning Jupiter's average diameter is 10.86 times that of the Earth's (10.49 time at the poles and 11.22 times at the equator).

With a radius of 15,299.4 miles (24,622 kilometers), Neptune is about four times wider than Earth. If Earth were the size of a nickel, Neptune would be about as big as a baseball. From an average distance of 2.8 billion miles (4.5 billion kilometers), Neptune is 30 astronomical units away from the Sun.

Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. It has an equatorial radius of 24,900 kilometers (about 1.4 Earth radii).

The equatorial gravity of the planet, 896 cm (29.4 feet) per second per second, is only 74 percent of its polar gravity. Saturn is 95 times as massive as Earth but occupies a volume 766 times greater. Its mean density of 0.69 gram per cubic cm is thus only some 12 percent of Earth's.

Inches of mercury or inHg is a non-SI unit for pressure. ... Aircraft operating at higher altitudes (above 18,000 feet) set their barometric altimeters to a standard pressure of 29.92 inHg or 1,013.2 hPa (1 hPa = 1 mbar) regardless of the actual sea level pressure, with inches of mercury used in the U.S. and Canada.
