Recent findings have revealed that the newly discovered asteroid, 2023 FW13, is not just any ordinary asteroid passing by. Astronomers have uncovered that it is an ancient companion of Earth, categorised as a quasi-moon, and has been orbiting near our planet since 100 BC.
It is expected to continue orbiting Earth until AD 3700, indicating that it will accompany our planet in its journey through space for several millennia.
Scientists discovered a new 'quasi-moon' orbiting Earth
Further, astronomers believe that this newly founded quasi-moon will stick with Earth until at least A.D. 3700, meaning it will travel through the cosmos with Earth for several thousand years to come.
Astronomers believe asteroid 2023 FW13 shares a similar orbit to another quasi-moon that is known as Kamoʻoalewa (2016 HO3). The asteroid is estimated to be around 65 feet (20 meters) wide. While it sticks with Earth during its orbit, astronomers say that the Sun has a much higher influence on it.
Nasa's new interactive map of Mars lets you tour the red planet - BBC Newsround
If you have ever dreamt of being able to walk on Mars, Nasa's new interactive map of the red planet is a step in the right direction.
The MRO is a space craft that has been orbiting the planet since 2006, sending back data to scientists on Earth.
All the information the satellite has collected has now helped a team of experts create an almost complete picture of Mars.

New Planet-Hunting Technique Finds Worlds We Can See Directly - Scientific American
When astronomers discovered the first worlds orbiting other stars thirty years ago, they also began taking what might be called the galactic planetary census , tallying up the numbers and types of exoplanets in the Milky Way.
But there are several different ways to find planets, and each tends to work best for different types of worlds, leading to potentially skewed results.
Rare Glimpse of Alien World Revealed in Planet-Hunting Breakthrough
The motion of a star as it makes its way through the galaxy has led to the discovery of a new alien world.
Using data from the Gaia spacecraft that's mapping the Milky Way, astronomers detected a kink in the motion of a star named HIP-99770, suggesting the presence of a nearby planet.
