All of us may have considered what if we aren?t the only intelligent form of life in the universe. What if, light years away, are living beings who think and act like us? Or maybe beings with way, way advanced technology, and are studying us from afar? Some people doubt the existence of extraterrestrial life, but we also don?t have any evidence that life elsewhere in the universe do not exist.
A terrestrial planet is a planet which has solid surfaces and is primarily composed of silicate racks and/or metals. There are 4 known terrestrial planets in our solar system – Mercury, Venus, Earth and Mars, which are all inner planets and one terrestrial dwarf planet, Ceres, located in the asteroid belt. These planets share similar characteristics such as proximity to the soon, few or no moons, absence of planetary rings such as Saturn’s, relatively weaker magnetic fields and closely spaced […]
The planet Mars that is otherwise referred to as the “Red Planet” is the fourth closest planet to the sun within our solar system. Its name, Mars, is actually taken from the Roman’s god of war. It has been described as the red planet because of the prevalence of iron oxide on its surface that makes it entirely appear as reddish. In comparison to the planet Earth, Mars has a lesser density. It approximately has 15% of the volume of […]
Mars, is considered as the Earth’s closest neighbor, holds quite a few similarities to Earth. These include having volcanoes such as the biggest Olympus Mons, valleys such as the Valles Marineris which stretches 2/3 across the planet (or from New York to LA on Earth) and even deserts. Although the 4th planet from the sun is only half the size of Earth, Mars has both North and South poles with white polar ice caps. However, in recent studies, scientists have […]
Is there one person who was credited to the discovery of Mars? Strictly speaking, no one actually discovered Mars. Or, rather, there is no specific person who pointed out that Mars existed. Out of the seven other planets in the solar system, five is visible from the Earth. These five—Mercury, Venus, Mars, Jupiter, Saturn—have been known to exist ever since the pre-historic era. The fact that these objects were actually planets and just like Earth isn’t known, needless to say. […]
Mars’ atmosphere is thinner compared to that of earth. The atmospheric pressure on Mars depends on how high or low the land is elevated. On Olympus Mon’s peak, Its pressure is at 30 pascals (0.0044 psi) and in the lowest point of Hellas Planitia it can get as high as 1,155 pascals (0.1675 psi). Its average pressure would be 600 pascals (0.087 psi). The scale height of Mar’s atmosphere is around 6.8 miles (11 km).
Just like Venus, Planet Mars is known for its brightness, which is why it can be easily spotted and seen by anyone in the sky at night. Because of this fact, the first exact person to who discovered the planet is unknown. The only thing that every person knew about the planet is that its name was taken from the god of war of Romans due to the presence of its reddish color that can be compared to blood.
Mars is ten times less massive than that of Earth. It is the second smallest planet in the Solar System. The mass of Mars is 7.08 x 1020 tons or 6.42 X 1020 metric tons. Mars total density is 3.933 grams/cubic centimeter. The diameter of Mars is 6,792 kilometers. To illustrate these characteristics, Mars density is similar to that of the Earth’s moon. Mars is just 4/5 of the earth’s density.
