We’ve previously discussed different crystals and rocks and what their spiritual and healing properties are. Nevertheless, they are all from our planet Earth.
So, what rocks and crystals can we find in the rest of the universe? What are other planets made of?
What Planets Are Made Of
The Earth is made of common minerals, such as feldspars and metals like magnesium and aluminum. The other rocky planets of our Solar System, Mercury, Venus and Mars, are also believed to have a relatively similar composition as Earth. Not as much is known about Mercury though due to the lack of exploration.
In Venus’ case, the planet is surrounded by very thick gases which makes it hard to observe. When scientists were finally able to send probes to the planet, they discovered that the surface was very dry with a burning landscape. Its crust is probably mostly basalt because of the volcanic activity.
Basalt is an igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava.
As for Mars, which is famous for its red color, it is made up of iron oxide, also known as rust. This oxide covers the surface of the entire planet and is responsible for the planet’s unique color.
Opal has also been found on Mars which helped lead to the discovery that this planet once had water since Opal requires water to form.
The other planets of our Solar System, the gas giants, Jupiter, Saturn, Neptune, and Uranus, are mostly composed of hydrogen and helium and don’t have a rocky surface.
Nevertheless, it is believed that on Saturn and Jupiter, the atmosphere combined with the great pressure can forge diamonds up to 1 centimeter in diameter.
Moon rocks were collected on different Apollo missions that NASA carried out and in which the astronauts managed to bring to Earth hundreds of kilograms of our natural satellite’s material.
There are two main categories of moon rocks which are those found in the highlands, called terrae, and those found in the maria. Their composition consists of basalt, similar to the volcanic rocks on Earth, but much richer in magnesium, iron and glassy structures that are indicative of rapid cooling.
Another interesting fact is that moon rocks contain no water!
While you may not easily be able to own a moon rock anytime soon even if we have plans of building human settlements on the moon one day, you can easily acquire a moonstone! It is considered to be the fertility crystal and its name comes from its similarity to the moon.
Owning a beautiful moonstone is like having a drop of moonlight in your hands (or ears if you prefer wearing moonstone earrings instead)!
Nevertheless, the Moon does have some pretty shiny crystals and not just volcanic rocks. In 2010, a planetary scientist from Brown University found a rock containing the mineral plagioclase that also included pink spinel which is very valuable here on Earth.
Rocks From Other Solar Systems
In 2013, a very mysterious rock, named Hypatia, was found in Egypt and scientists have concluded that it had to be formed at a time when even our own sun didn’t exist yet. Scientists based their conclusion based on rock’s composition which not only has never been seen on Earth before, but due to the fact that such a rock could only be formed at a temperature below that of liquid nitrogen on Earth (-196 Celsius)
According to scientists, not even an object such as the most distant planet from us, Neptune, would have experienced such low temperatures where a rock like this could be found.
This leaves the question of how it got here!
Last year, for the first time in recorded history, a chunk of rock and ice appeared to target our planet from another solar system.
Though it never reached Earth, it went right past us at more than 98,000 miles an hour. Scientists believe that it could have been a part of an alien planet that doesn’t exist anymore.
Not only are planets made of minerals, but they also have precious crystals as scientists have discovered.
There is a planet, 40 light years away from Earth, made entirely of diamonds. Its name is 55 Cancri e and it’s double the size of Earth with its year lasting a mere 18 hours.
Also, it is known that crystals called cristobalite and tridymite swim in clouds around stars just before they begin to form planets, so they’re just like diamonds in the sky!
Emerald city? Yes, it exists, but it’s a young star 1,350 light years away from us. A telescope from NASA detected that this star has crystal rain made of olivine which is also known as peridot.
Finally, the unique black diamond has been confirmed to come from outer space. Unlike regular diamonds formed on Earth, their black version is formed because of a supernova exploding. Amazing, isn’t it?
