Earth Is Temporarily Getting a 2nd Moon
Earth will get a second "mini-moon" for 2 months this year
The asteroid was discovered in August and is set to become a mini-moon, spinning around Earth in a horseshoe shape for about two months.
What you need to know about Earth’s new, temporary mini-moon
Here’s what to know about our new, temporary celestial neighbor. Earth has a large gravitational pull. So it’s not uncommon for objects flying through space to be attracted to it or get caught up in an orbit — at which point they earn status as miniature moons. The same happens with objects purposefully placed in space, such as satellites.
Earth Is Temporarily Getting a Second ‘Moon’
Sadly, at just about 10 meters, the mini-moon will be extremely hard to see from Earth, but its presence will be there nonetheless for almost two months. The asteroid, which was discovered on Aug. 7 by NASA, originated from the Arjuna asteroid belt, where it will likely return once it leaves Earth’s orbit.
Study reveals Earth once had rings similar to Saturn's
Earth May Have Had a Ring Like Saturn Once
“Over millions of years, material from this ring gradually fell to Earth, creating the spike in meteorite impacts observed in the geological record,” said Tomkins in a statement that accompanied the paper’s release. “We … see that layers in sedimentary rocks from this period contain extraordinary amounts of meteorite debris.”
Earth used to have Saturn-like rings, new study suggests
Earth and Saturn might be a lot more similar than previously thought. In a new study, a team of researchers suggests that 466 million years ago, a ring system made up of asteroid remnants may have surrounded our planet,
Earth May Have Once Had a Saturn-Like Ring, New Study Says
And now, a new study published in the scientific journal Earth and Planetary Science Letters seems to show that Earth itself once had a similar ring. The new study asserts that Earth's ring formed around 466 million years ago and stuck around for around 40 million years before dissipating.
