Meet Earth’s newly-discovered companion, a mini-moon named 2020 CD3
Earth has a new companion: a mini-moon called 2020 CD3. On Feb. 15, scientists discovered a small rocky chunk that was captured by our planet’s gravity. But don’t get too excited, because it’s likely only a temporary fixture.
Our planet has only one natural satellite, our moon, but for the last couple of years, there’s been another lurking out in space. Astronomers spotted what is likely a carbonaceous asteroid with the help of the Catalina Sky Survey. The mini-moon is between 6.2 and 11.5-feet (1.9 to 3.5-m) in diameter, and roughly the size of a car.
Typically, temporarily captured objects, like 2020 CD3, only hang around for a brief time (from a few months to a year or two) before they are flung back out into space, or in some cases, burn up in our planet’s atmosphere as they’re pulled in by Earth’s gravitational tug. But according to astronomer’s, it’s been orbiting the Earth for up to three years now.

The celestial real estate encircling the Earth is pretty crowded, which is probably why we’ve just now noticed it. Asteroids — which are piles of planetary rubble, remnants left over from the birth of the solar system — are usually very small and dark, making them difficult to spot.
So, discovering 2020 CD3 is kind of a big deal. To date, there have been only a handful of proposed potential mini-moons with only one confirmed — an asteroid named 2006 RH120. The three-foot-wide space rock orbited the Earth for just over a year, from 2006-2007.
“Out of 1 million known asteroids, this is just the second asteroid known to orbit Earth,” Kacper Wierzchos, the astronomer who detected the object, said on Twitter.

The existence of 2020 CD3 is an exciting discovery for a number of reasons, including providing the chance to study asteroids up close. Most asteroids orbit between Mars and Jupiter, in the main asteroid belt and it takes sending a spacecraft out into the solar system to study one of these celestial objects in detail.
2020 CD3 could provide astronomers with the chance to study asteroids in detail and better understand how they’re captured by planets. Unfortunately, computer simulations indicate that the mini-moon could be back on a journey around the sun as early as April. That’s because it’s caught in a game of tug-of-war between the Earth and the moon.
Analysis of 2020 CD3’s orbital motion indicates it’s heavy for its size, which leads astronomers to believe it is in fact, an asteroid. But scientists will use the next few weeks to continue studying the enigmatic object in order to definitively determine whether it is indeed an asteroid or perhaps a rogue piece of space junk.
There’s no time to plan a mission to 2020 CD3, as the object is already growing fainter and fainter in images, but astronomers say it will likely be back in a few decades. With more advanced telescopes coming online in the near future, these types of sightings could become more and more common.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
-
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
