Recent research indicates that a rare meteorite, dated at four-and-a-half billion years old, provides insights into a massive planet that may have existed in the early solar system.
This planet, possibly comparable in size to the moon or Mars, is believed to have orbited the sun before it collided with another celestial body, resulting in its fragmentation.
The findings were published in the journal Earth and Planetary Science, shedding light on the complex history of our solar system's formation.
