Most of the planets in the solar system have multiple moons but the sapphire of the world is the same.
However, another small moon has entered the orbit of the earth as a momentary guest.
Astronomers say it is actually an asteroid the new orbit name is 2020CD3.
However, this moon has not come to orbit the earth for as long as our moon.
Its diameter ranges from 1.9 m to 3.5 m. that is.
The shape is slightly larger than a cow and slightly smaller than a hippopotamus.
The dwarf moon was first spotted through a telescope from the International Astronomical Union’s Minor Planet Center.
The Minor Planet Center of the International Astronomical Union is responsible for observing, researching, and naming all the planets in the solar system.
Caspar Wieskhorse is an astronaut at the Minor Planet Center of the International Astronomical Union.
He recently tweeted about this 2020 CD3 Caspar a member of the Catalina Sky Survey team his colleagues first discovered the asteroid on February 15.
Caspar said there are millions of such asteroids.
However, this is the second time in the history of space that the Earth has entered orbit.
Earlier, an asteroid named RH120 entered the Earth’s orbit for a few days. Also orbited the earth.
That too first caught the eye of the members of the Catalina Sky Survey.
What exactly caused this asteroid to come into Earth orbit?

Scientists say that this could be due to the combined force of gravity of the earth, moon, and sun.
Astronomers estimate that 2020 CD3 has been orbiting the Earth for the past three years.
The orbit will change again between October 2020 and May 2021.
The asteroid is likely to come closer to Earth early next year 2021.

However, says it may not be something cosmic.
Scientists there have speculated that the object may have been an old booster rocket from the 1960s.
