Spending a Day on Earth 200 Million Years Ago

Earth 200 million years ago was a very different place from now, for starters, Earth only had one continent Pangaea which later with tectonic plates moving split into many more continents that we have today. So, all of today’s continents can fit inside Pangaea almost perfectly. Pangaea was surrounded by a gigantic ocean Panthalassa or […]

What If Earth Became a Moon of Saturn

Saturn sixth planet from the Sun and the  second largest planet in the solar system, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It has only one-eighth the average density of Earth, but with its larger volume Saturn is over 95 times more massive. Saturn is named after the Roman god of agriculture, its astronomical symbols (h) represents the god’s sickle. Saturn’s interior is probably composed of a core of iron-nical and rock (silicon and oxygen compounds). This core is surrounded by a deep layer of metallic hydrogen an intermediate layer of liquid hydrogen and liquid helium,  and finally a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. Electrical current within the metallic hydrogen layer is thought to give rise to Saturn’s planetary magnetic field, which is weaker than Earth’s but has a magnetic moment 580 times that of Earth due to Saturn’s larger size.

What If Venus Became a Moon of Earth

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has the longest rotation period (243 days) of any planet in the Solar System and rotates in the opposite direction to most other planets. It has no natural satellites. It is named after the Roman goddess of love and beauty.  It is the second-brightest natural object in the night sky after the Moon, reaching an apparant magnitude of −4.6 – bright enough to cast shadows at night and, rarely, visible to the naked eye in broad daylight. Orbiting within Earth’s orbit, Venus is an inferior planet and never appears to venture far from the Sun. It is the hottest planet in the solar system despite its being second closest planet to the Sun. It is a hell world what average temperature being 462 Celsius or 2 times more than the average oven, even though Mercury is closer to the Sun. Read more about What If Venus Became a Moon of Earth

What If Titan Were a Moon of Earth

Titan is the largest moon of Saturn. It is the only moon known to have a dense atmosphere, and the only object in space other than Earth here clear evidence of stable bodies of surface liquid has been found. Titan is the sixth ellipsoidal moon from Saturn. Frequently described as a planet-like moon, Titan is 50% larger than Earth’s Moon, and it is 80% more massive. It is the largest second-moon in the Solar System, after Jupiter’s moon Ganymede and is larger than the smallest planet, Mercury but only 40% as massive. Discovered in 1655 by the Dutch astronomer Christiaan Huygens, Titan was the first known moon of Saturn, and the sixth known planetary satellite(after Earth’s Moon and the four Galilean moons of Jupiter).

What If Europa Became a Moon of Earth

Europa, moon of a gas giant Jupiter. Europa is the smallest of the four Galilean Moons orbiting Jupiter, and the sixth-closest to the planet. It is also the sixth-largest moon in Solar System. Europa was discovered in 1610 by Galileo Galilei and was named after Europa, the legendary mother of King Minos of Crete and lover of Zeus (the Greek equivalent of the Roman god Jupiter). Slightly smaller than Earth’s Moon, Europa is primarily made of Silicate rock and has a water-ice crust and probably an iron-nickel core. It has a tenuous atmosphere composed primarily of oxygen. Its surface is striated by cracks and streaks, whereas craters are relatively rare. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath it, which could conceivably harbor extraterrestrial life. The predominant model suggests that heat from tidal flexing causes the ocean to remain liquid and drives ice movement similar to plate tectonics, absorbing chemicals from the surface into the ocean below.

If Mars Became a Moon of Earth

Mars the Red Planet even though taking a better look at it it’s quite colorful planet. In English, Mars carries a name of the Roman god of war, It is the second smallest terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. In our solar system,but that doesn’t mean that it’s not a big place. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos  and  Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan. It has the similar solid surface area (Total and Solid: 144,800,000 km2) as Earth  (Solid : 148,940,000 km2, Total : 510,072,000 km2). If we include the oceans it has about half the diameter of Earth (Mars : 6,779 km, Earth : 12,742 km),  also you can fit two of them in Siberia. There are ongoing investigations assessing the past habitability potential of Mars, as well as the possibility of extant life.

What would happen if Pluto Became a Moon of Earth

Pluto a dwarf planet located far reaches of the solar system in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered. Pluto was discovered by Clyde Tombaugh in 1930 and was originally considered to be the ninth planet from the Sun. After 1992, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt. In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term “planet” formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet. It has a moderately eccentric and inclined orbit during which it ranges from 30 to 49 astronomical units or AU (4.4–7.4 billion km) from the Sun. This means that Pluto periodically comes closer to the Sun than Neptune, but a stable orbital resonance with Neptune prevents them from colliding. Light from the Sun takes about 5.5 hours to reach Pluto at its average distance (39.5 AU). On average it is 40 times more distant from the sun than earth is. It’s surface area is 17,600,000 km, which is slightly bigger than Russia’s 17,100,000 km. If you put it into real perspective you can fit 150 pluto into earth, So what if this small dwarf planet were to become a moon of Earth, that would mean that Pluto would need to get closer to the Sun which would provide quite a few drastic  changes to its surface. Pluto has five known moonsCharon (the largest, with a diameter just over half that of Pluto), StyxNixKerberos, and Hydra. Pluto and Charon are sometimes considered a binary system because the barycenter of their orbits does not lie within either body. Read more about What would happen if Pluto Became a Moon of Earth
