Earth will get a second moon for about two months this year when a small asteroid begins to orbit our planet. The asteroid was discovered in August and is set to become a mini-moon, revolving around Earth in a horseshoe shape from Sept. 29 to Nov. 25.

Researchers at the Asteroid Terrestrial-impact Last Alert System, an asteroid monitoring system funded by NASA, spotted the asteroid using an instrument in Sutherland, South Africa and labeled it 2024 PT5. 

Scientists from the Universidad Complutense de Madrid have tracked the asteroid’s orbit for 21 days and determined its future path. 2024 PT5 is from the Arjuna asteroid belt, which orbits the sun, according to their study published in Research Notes of the AAs. 

But Earth’s gravitational pull will draw 2024 PT5 towards it and, much like our moon, it will orbit our planet – but only for 56.6 days.

While other non-Earth objects – or NEOs – have entered Earth’s orbit before, some don’t complete full revolutions of Earth. Some, however, do and become so-called mini moons.

An asteroid called 2020 CD3 was bound to Earth for several years before leaving the planet’s orbit in 2020 and another called 2022 NX1 became a mini-moon of Earth in 1981 and 2022 and will return again in 2051. 

2024 PT5, which is larger than some of the other mini-moons, will also return to Earth’s orbit – in 2055. 

Earth’s gravity will pull it into its orbit and the asteroid will have negative geocentric energy, meaning it can’t escape Earth’s gravitational pull. It will orbit around earth in a horseshoe shape before reverting back to heliocentric energy, meaning it will rotate around the sun again, like the other planets and NEOs in our galaxy.

Even after it leaves orbit, it will stay near Earth for a few months, making its closest approach on Jan. 9, 2025. Soon after, it will leave Earth’s neighborhood until its path puts it back into our orbit in about 30 years.

The study’s lead author Carlos de la Fuente Marcos told Space.com the mini-moon will be too small to see with amateur telescopes or binoculars but professional astronomers with stronger tools will be able to spot it.

CBS News has reached out to Marcos for further information and is awaiting response.

Washington — An Alaska man was arrested Wednesday for allegedly threatening to assassinate six members of the Supreme Court and harm two family members, the Justice Department said.

Panos Anastasiou, 76, is accused of sending more than 465 messages to the Supreme Court through an online portal, which included violent, racist, and homophobic rhetoric, according to court filings. Anastasiou allegedly threatened to assassinate, kidnap, torture, hang, behead and execute the justices, and encouraged other people to join him in committing acts of violence, the Justice Department said.

He faces nine counts of making threats against a federal judge and 13 counts of making threats in interstate commerce. Anastasiou appeared before a federal magistrate judge Wednesday and pleaded not guilty.

“We allege that the defendant made repeated, heinous threats to murder and torture Supreme Court Justices and their families to retaliate against them for decisions he disagreed with,” Attorney General Merrick Garland, a former federal appeals court judge, said in a statement. “Our justice system depends on the ability of judges to make their decisions based on the law, and not on fear. Our democracy depends on the ability of public officials to do their jobs without fearing for their lives or the safety of their families.” 

The Supreme Court declined to comment on the charges. An attorney for Anastasiou was not listed in court records.

The targeted justices are not named in the indictment and identified only as “Supreme Court justices 1-6.” Charging documents state that some of the threats allegedly made by Anastasiou “were intended to intimidate” the justices and “retaliate against them for official actions” they had taken in their capacity as judges.

The messages were sent between January and July, when the Supreme Court ended its term, court documents. 

In one of the messages, sent Jan. 4, Anastasiou allegedly threatened to murder one justice by “providing the rope” to “hang … from an Oak tree.” Another on May 10 included a threat to kill the same justice by “lynching.”

Court filings state that in a May 16 message referring to a second member of the Supreme Court, Anastasiou allegedly threatened to kill the justice by “putting a bullet in his … head.” The Justice Department said a message sent the following day was targeted not only at the first two justices, but also two unnamed family members and warned of sending “fellow veterans” to “spray” their houses with bullets with hopes of killing them.

The Supreme Court has a 6-3 conservative majority and has come under immense criticism in recent years for decisions on politically charged issues including abortion, guns and presidential power. In its most recent term, the six conservatives voted to find former President Donald Trump is entitled to immunity from federal prosecution for official acts undertaken in the White House.

Its June 2022 decision unwinding the constitutional right to abortion was highly criticized and led to protests outside the homes of several conservative justices, including Justices Samuel Alito, Amy Coney Barrett and Brett Kavanaugh. A California man was arrested in June 2022 after he was found outside of Kavanaugh’s Maryland house with a gun, knife and various tools, and charged with threatening to assassinate the justice. He pleaded not guilty.
