November 25 was a busy day for aliens. According to NASA, two asteroids are approaching the Earth and can be considered a 39 near-world object ast (NEO). One of the NEOs called 2018 VT7 is about 20 to 60 meters in diameter, typically a typical type of object close to our planet.
However, the other NEO, called WHB105, is humus with a diameter of 170 feet and 400 feet in size. The maximum calculated asteroid is larger than the Statue of Liberty and longer than a football field.
The 2018 VT7 asteroid came within 2 million miles of the Earth, which can be considered as cosmologically close. Fortunately, the larger asteroid will be 3.5 million miles away, so it won't be a concern for the Earth. Objects on earth are orbiting around 120 million miles around the Sun.
The asteroids consist of debris from events such as birth or death of stars and planets, and most of the asteroids in our solar system are composed of inner planets such as Venus and Mars.
Another use of these objects on earth is because they are made up of minerals that are hard to find in the world, and uses them for resources. These materials can be a way to produce rocket fuel and remove it to produce new space structures.
