- The first known permanent population of asteroids has been discovered in the new study.
- The study has been published in the journal Monthly Notices of the Royal Astronomical Society.
- It was discovered between Jupiter and Neptune by the Brazilian Astronomers.
- It roams in between the giant planets of the solar system.
- The first interstellar asteroid known as 'Oumuamua was discovered in 2017.
- The asteroid has come from the star called Vega in the constellation Lyra.
- The asteroids belong to a group of objects called Centaurs.
- The asteroids have been originating from outside of our solar system.
- It is believed that the asteroids have been captured from other stars billions of years ago.
- As the universe began to expand, the sun was born and the gravity of the growing sun sucked these asteroids into the solar system.
- These asteroids once belonged to another star and are now orbiting between Jupiter and Neptune.
- They have been orbiting our sun and hiding in plain sight.
- The newly discovered asteroids are believed to have been present almost since the birth of our solar system, 4.5 billion years ago.
- The close proximity of the stars meant that they felt each other's gravity much more strongly in those early days than they do today.
- This enabled asteroids to be pulled from one star system to another.
- Astronomers believe the space rocks were ripped from their original location as the universe expanded and the sun grew rapidly, creating its own gravitational pull.
- The enormous force of the burgeoning star sucked the rocks into the formative solar system and they have remained here ever since.
