The Earth is due for an asteroid flyby today, as a chunk of space rock is forecast to soar past the planet at a closer distance than the moon.
The asteroid, named 2023 LZ, is predicted to pass the Earth at a distance of 0.00212 astronomical units or A.U.—one A.U. is the distance between the Earth and the sun, or around 93,000,000 miles.

An asteroid roughly as long as Chicago's Willis Tower is tall is set to pass by Earth tomorrow. It poses no threat to our world, like it or not.

Now, researchers analyzing a sample returned 13 years ago from the peanut-shaped asteroid Itokawa have "seen" a possible source of Earth's water in a crystal of salt.
"The discovery of sodium chloride in a sample from an S-type asteroid means that this asteroid could contain abundant water during its formation and evolutionary history," said lead author Shaofan Che, a postdoc at University of Arizona's Lunar and Planetary Laboratory (LPL).

Scientists have discovered salt crystals in samples from asteroid Itokawa , collected by Hayabusa in 2010. The space rock is an S-type asteroid, which as a class has been considered quite dry, with little water alteration in its past.
"Once these ingredients come together to form asteroids, there is a potential for liquid water to form," Tom Zega, the study's senior author and a professor of planetary sciences at the University of Arizona Lunar and Planetary Laboratory, said in a statement .
