Rarely Known Moon Facts - As we all know, the moon is a celestial body that can emit its own light at night. The round shape of the moon was able to light up the night. The moon can be seen with the naked eye at night. The info, the moon is a celestial body that is very close to the earth. Here are some facts about the moon that are rarely known.
1.Origin of the month
The moon was created when a rock the size of Mars hit Earth, shortly after the solar system began to form about 4.5 billion years ago.
2. Moon locked in orbit
Perhaps the coolest thing about the moon is that it always shows us the same 'face' surface. Since the Earth and moon rotate and orbit, how did this happen? Long ago, the effect of Earth's gravity slowed the rotation of the moon around its axis. Once the moon's rotation slows down enough to match its orbital period (the time it takes the moon to circle the earth), the effect stabilizes. Many moons around other planets behave similarly. What about phases? Here's how it works: As the moon orbits Earth, it spends some of its time between us and the Sun, and half the light away from us. This is called the new moon. (So there's no such thing as a "dark side of the moon," only the side we never see.) As the moon rotates in its orbit, a thin sliver of reflected sunlight is visible on Earth as a crescent moon. As soon as the Moon is opposite the Sun, it becomes brightly lit in our view - the full moon.

3. Moon... tree?
More than 400 trees on Earth are from the moon. All right: They came from lunar orbit. The truth is that in 1971, Apollo 14 astronaut Stuart Roosa carried a bundle of seeds with him, while Alan Shepard and Edgar Mitchell were busy strolling the surface, Roosa guarding the seeds. Then, the seed was brought back to earth and planted in various places throughout the land, and was later called the moon tree. The condition of the trees is fine.
4. Earth Moon Sister
The Moon is Earth's only natural satellite. Well? Probably not. In 1999, scientists discovered that an asteroid 3 miles (5 kilometers) wide may be trapped in the grip of Earth's gravity, thus becoming a satellite of our planet.
5. Space stone
The cratered surface of the moon is the result of a massive blow from space rocks between 4.1 billion and 3.8 billion years ago. These war scars, which appear as craters, have not eroded much for two main reasons. The moon is not very active geologically, so earthquakes, volcanoes, and mountain building do not destroy the landscape as they do on Earth; and with almost no atmosphere, no wind or rain, so very little surface erosion occurs.
6. The moon is shaped like an egg
The moon is not round. The moon is shaped like an egg. If you go outside and look up, one of the small ends is pointing right at you. And the moon's center of mass is not at the satellite's geometric center; it's about 1.2 miles (2 kilometers) from the center.
1. Purple bubbles/Fermi Bubbles
In November 2010, astronomers using NASA's Fermi Gamma-ray Space Telescope discovered two bubbles made of gamma rays. The size of the bubble is about 2.2 million mph (3.5 million km/h).
Two bubbles were found, above and below the black hole in the Milky Way's core. These two bubbles touch each other, like an hourglass. The whole structure looks like the number 8.
2. White holes and black holes
Space has black holes that are immeasurably vast. But there are black holes (black holes), there are also white holes or white holes. According to researchers' estimates, the existence of white and black holes is like Yin and Yang, has 2 different things. If a black hole will suck an object in, then a white hole will expel that object.
However, there are no known signs of the existence of this white hole. Why? Because nothing is spewed out by a white hole. Until now researchers are still detecting unusual radiation explosions will later be developed hypotheses about white holes.
1. Greenwich Observatory, England
The Royal Observatory Greenwich is one of the best observatories owned by the UK. As written in the Britannica, the observatory was founded in 1675 by the King of England, Charles II.
At that time, this ancient observatory served as a place for observing star positions, navigation, timekeeping, and almanac (calendar) publications. During the 1997 financial crisis, there were cost cuts which resulted in the observatory closing in 1998.
Today, the Greenwich Observatory is open to the public and is included in one of the facilities in the National Maritime Museum. This space observation spot is frequented by astronomy-loving tourists from all over the world every year.
2. Paranal Observatory, Chile
If one day you travel to Chile, you can visit one of the world's best observatories called The Paranal Observatory. This observatory was built quite magnificently and has advanced technology.
Astronomic Tourism on its website writes that this facility building was erected at an altitude of 2,630 meters above sea level. Inaugurated by the president of Chile in 1996 ago, the construction of this observatory has cost Rp. 3.3 trillion.
No kidding, this observatory is equipped with 4 VLT (Very Large Telescope) and 1 VLTI (Very Large Telescope Interferometer) unit. The advantage of this telescope is that it can see the expanse of bright objects in the sky evenly with high resolution so that celestial objects can be seen in detail.
2. Transit of Venus
Venus once passed in front of the sun as well as between the sun and the earth. Make it like a black dot in the sun. This is called a transit of Venus.
Venus transit phenomena always occur in pairs, with a patterned span of about 8 years. The events that occurred in 2004 and 2012 are indeed quite rare. A similar Venus transit pair will occur again in about 105 years, namely in 2117 and 2125.
3. Tetrad Bloodmoon
This event is quite rare. During the calculation of the Gregorian calendar, this event only happened seven times. A similar event is expected to return in 2033.
