location From The Sun...

• "At its closest (perihelion), Mars is 128 million miles (206 million km) distant. On average, the distance to Mars from the sun is 142 million miles (229 million km), according to NASA."

Mars: Inner or Outer Planet?

• "Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune."

mars vs. earth

• "This image compares Mars and Earth in their correct relative sizes. Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets."

Description of mars

• ''Mars is the fourth planet from the Sun and is the second smallest planet in the solar system. Named after the Roman god of war, Mars is also often described as the “Red Planet” due to its reddish appearance. Mars is a terrestrial planet with a thin atmosphere composed primarily of carbon dioxide.''
• ''Physical Characteristics of Mars. Mars has approximately half the diameter of Earth.''

rotation of mars

• ''Orbit and Rotation on Planet Mars. Mars' average distance from the Sun is roughly 230 million km (1.5 AU) and its orbital period is 687 (Earth) days. The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds.''
• ''Mars rotation is 24 hours, 39 minutes, and 35 seconds if you are interested in the solar day or 24 hours, 37 minutes and 22 seconds for the sidereal day.''

rotation around the sun

• ''Mars revolves or orbits around the Sun once every 1.88 Earth years, or once every 686.93 Earth days. Mars travels at an average speed of 53,979 miles per hour or 86,871 kilometers per hour in its orbit around the Sun.''
• ''The orbit of Mars is more oval-shaped than that of the Earth.''

what is mars made up of ?

• ''Mars is the "Red Planet" for a very good reason: its surface is made of a thick layer of oxidized iron dust and rocks of the same color. Maybe another name for Mars could be "Rusty." But the ruddy surface does not tell the whole story of the composition of this world.''

atmosphere of mars

• ''The Martian atmosphere contains about 95.3% carbon dioxide (CO2) and 2.7% nitrogen, with the remainder a mixture of other gases. However, it is a very thin atmosphere, roughly 100 times less dense than Earth's atmosphere.''
• My weight on Earth is 121.4 pounds, so, on Mars I would weigh 45.7 pounds

Satellites and rings

• ''Rings and moons. Definition. Rings and moons are the matter that orbit a celestial body other than a star. Rings are a collection of dust or small particles that form into a flat disk. Moons, or natural satellites, are much larger single bodies.''
