November 25 was a busy day for the aliens. According to NASA, two asteroids have passed near Earth and can be considered a "near object of the Earth" (NEO). One of the NEOs, called 2018 VT7 is about 20 to 60 feet in diameter, which is a typical type of object that usually passes close to our planet.
However, the other NEO named 2009 WB105 is of considerable size, measuring 170 feet and 400 feet across. At its maximum calculated size, the asteroid is larger than the Statue of Liberty and larger than a football field.
The 2018 VT7 asteroid has reached 2 million miles from Earth, which can be considered close in cosmological terms. Fortunately, the largest asteroid will be 3.5 million miles away, so it will not be a concern for Earth. The objects near the Earth are those bodies that are in an orbital path around the Sun in a radius of 120 million kilometers.
Asteroids are formed from the debris of events such as birth or death of stars and planets, and most of the asteroids in our solar system are formed by internal planets such as Venus and Mars.
Another use of these near-Earth objects is to use them for resources because they are composed of minerals that are difficult to find on Earth. There may be a way to extract these materials to generate rocket fuel and produce new spatial structures.
