Asteroid RQ36 Could Tell How Solar System Came To Be
The asteroid 1999 RQ36 may be able to tell scientists how the solar system was born, and perhaps, shed light on how life began. The chunk of rock and dust, about 1,900 feet in diameter, also might hit us someday, according to NASA researchers studying the asteroid. Asteroids are leftovers from the cloud of gas and dust – the solar nebula -- that collapsed to form our sun and the planets about 4.5 billion years ago. As such, they contain the original material from the solar nebula, which can tell us about the conditions of our solar system's birth. In some asteroids, this material was altered by heat and chemical reactions, either because they collided with other asteroids, or because they grew so large that their interiors became molten. read more
