Mercury, Venus, Saturn, . Notice how all planets of the Milky Way are named after Gods and Goddesses of Greek and Roman Mythology?
The earth isn’t just a place where living things can survive and thrive as it is postulated to be a giant itself. The Gaia Hypothesis claims that the Earth is an organic system which has the ability to self-regulate in order to maintain life as we know it.
Another amazing feature of the Earth is that it has almost 500 volcanoes worldwide. About 80% ofthe Earth, that which is found above and below the surface, are made of volcanic soil.
One of the most interesting facts about Earth is that it used to have a twin planet, named Theia. Some 4.5 billion years ago, a planetary body which was postulated to be large as the planet Mars, shared the same orbit with Earth.
It was between the late 18th century and early 19th century that the Industrial Revolution boomed and flourished throughout developing countries across the globe.
The Earth is popularly dubbed as the Blue Planet. Astronauts who first went to space describe the entirety of Earth as blue. This is due to the fact that 71% of the planet is covered by bodies if water.
Aside from the sun as Earth’s main source of heat energy, humans could theoretically survive without the sun’s heat as the planet’s inner core is hot enough to supply energy to its .
Planet Earth is the only planet of the Milky Way which features tectonic plates.
The accurate of the Earth’s figure is oblate spheroid. This means that it is spherical, but also flattened from its two opposite poles.
Although water has been detected in neighboring planets, it is only on Earth that water can be found across three states of matter namely solid, water, and air.
We have approximately 24 hours in a day, but it is expected that after about 250 million years, a day will last 1.5 hours longer due to the slower rotation of the Earth around its axis.
Although it is known that Venus is the brightest celestial body in the sky, Earth is comparatively brighter when observed from outer space. The factor which makes our planet the brightest among all the planets of the Milky Way is water.
Pressure being released from the inner core and the constantly moving tectonic plates result in almost 1 million earthquakes per year; majority of which are never felt or recorded even by seismometers.
The Earth’s surface rotates on its axis at 1,000 miles per hour. Consequently, the planet travels through space at 66,700 miles per hour. But how come we do not feel that our planet is moving at a dizzying rate?
The occurrence of 4 seasons is not in any way related to the distance of the Earth from the Sun, but rather due to the way the planet is tilted on its axis. The obliquity or Earth’s tilt is currently at 23.4 degrees and is expected to change slightly over time.
From an altitude of 65 miles, the first photo of the Earth from space was taken using a 35-millimeter motion picture camera that was carried by Sputnik 2. It was in 1946 that the first discernible photo was made possible by a camera developed by the engineer, Clyde Holliday.
The pull of gravity differs all over the globe, depending on your distance from the earth’s core.
97% of water on Earth can be found in the oceans, while only 3% of water can be found in fresh water reservoirs and fresh water supply.
The Moon is not the only celestial body that rotates around our planet. Asteroids 3753 Cruithne and 2002 AA29 are also known to orbit the planet as well.
The Andes is popular to millions as it is known to be the largest and longest mountain range on Earth.
A supercontinent will be formed 25 million years from now. This is due to the constant movement of the tectonic plates. The of movement differs from one continent to another. In the Pacific, the plates move faster at 4cm per year, while the rate of movement in the North Atlantic is at 1cm annually.
There are approximately 30,000 space particles and dust that enter the Earth’s atmosphere annually. Fortunately, the majority of this debris burns up when it enters the earth’s atmosphere, resulting in shooting stars instead of giant craters.
It takes exactly about 8 minutes and 20 seconds for sunlight to reach the earth. This means that the heat and light that we see and feel on a warm, sunny day is emitted by the sun from 8 minutes past.
The core of the Earth can be found 3,700 miles down towards its center. The inner core is made up of a solid iron-nickel allow.
Although space missions are being deployed in outer space for the past few decades, these programs are primarily programmed to look for extraterrestrial life and space research. There are still no possibilities of life even with the nearest planetary body, Mars.
