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.

Investor's Corner

Tesla analyst’s firm has sold its entire TSLA position: Here’s why

Tesla analyst Gary Black revealed his firm, The Future Fund, has sold their entire $TSLA holding.

Tesla analyst Gary Black of The Future Fund revealed today that his firm has sold its entire $TSLA holding, marking the first time since 2021 that it has not had a position in the company’s stock.

Black has been a skeptic of the company and relatively pessimistic regarding some things many investors would consider catalysts, outlining his concerns and reasoning for selling the shares.

Much of Black’s reasoning concerns Tesla’s price-to-earnings ratio, delivery results and potential delivery figures for the future, and other near-term projects that he does not believe will yield as much value as others perceive.

We will break down each concern of Black’s below:

‘Disconnected from Underlying Fundamentals’

Black says that The Future Fund sold its holdings at $358 per share. The firm’s current price target is at $310, and he says it will remain there based on “our forecast of 2030 Tesla volumes of 5.4m and 2030 Adj EPS of $12.

Main Concern is P/E Ratio

The main concern Black and The Future Fund have is that TSLA “now sells at a 2025 P/E of 188x as earnings estimates continue to fall (-5% in the past week, -40% YTD) driven by weak YTD deliveries, including weak April results.”

Black says he believes quarterly deliveries will decline by 12 percent, and full-year by 10 percent.

This compares to Wall Street’s estimates of a 7 percent decrease for Q2 and a 5 percent year-over-year.

Robotaxi Skepticism

“We believe the risk/reward associated with the Austin robotaxi test remain asymmetrical to the downside,” Black writes in his post on X.

Many believe the Robotaxi platform could be Tesla’s biggest catalyst moving forward, especially as other automakers do not seem to have even close to as robust a solution to self-driving as Tesla.

Tesla’s Affordable Models

Black says there are concerns the affordable model will be “a stripped-down Model Y priced lower and funded by lower costs rather than a new form factory that expands TAM.”

This is confusing, especially considering the cheaper price tag would expand the total addressable market (TAM) to begin with. The Model Y has been the best-selling vehicle in the world for the past two years.

Tesla still on track to release more affordable models in 1H25

Introducing an even lower-cost model with some missing features would still likely be a significantly more attractive option than a base model ICE vehicle, especially because the value Full Self-Driving provides would make the car more beneficial.

“This increases odds that FY’25 estimates decline further, risking a repeat of 2023-2024, when TSLA reduced EV prices supported by lower costs, and TSLA saw little or no incremental volume growth,” he finishes with.

Tesla gets major upgrade that Apple users will absolutely love

Tesla is unloading a new feature for iPhone users that they will absolutely love.

Tesla is giving its owners who use iPhones and the iOS platform a major upgrade that will make the vehicles more compatible with the current capabilities of Apple devices.

Much to the chagrin of Android users, Apple iPhone users who own Teslas are usually the first to get new features.

However, Tesla is rolling out a new feature to iPhone users that will only be available to them, as Live Update compatibility is now rolling out.

Live Updates on the iPhone allow users to track the progress of tasks while using other apps. For example, uploading a post on X can be tracked while using an internet browser, as the Dynamic Island, the small display near the speaker on an iPhone, will show progress.

Tesla will now do this for Supercharging, a new update shows. The Dynamic Island is not the only thing that will monitor the progress of Supercharging, though. Updates will also be visible on the lock screen and as a drop-down notification:

You will need iOS 17.2 or newer to use this feature.

The Supercharging updates will show the current State of Charge (SoC), time remaining, and price of the current session. These notifications will make the charging process easier when you’re not inside your Tesla, as many Superchargers are located in retail settings.

You’ll be able to monitor the price and time remaining with a quick glance at your phone.

Tesla rolls out new crucial safety feature aimed at saving children

Tesla has been working on this child detection feature for several years.

Tesla is finally rolling out a new, crucial safety feature that is aimed at saving children from being left in the car.

Over the past few months, we have reported on a feature Tesla was planning to roll out in its vehicles that would help keep children out of hot cars unattended.

The company has been working on a solution to this problem for several years, as it has been working on an ultrawave sensor that would detect heartbeats instead of movement, as cameras would.

Now, Tesla is implementing the feature in its vehicles with Software Update 2025.14.12, calling it “Child Left Alone Detection.”

The release notes, via Not a Tesla App, show that the vehicle and the Tesla app will both make various attempts to alert the driver of a child in the car:

“If an unattended child is detected, the vehicle will flash the exterior indicator lights, play an alert tone, and send a notification to your Tesla app. This will repeat at regular intervals until you return to your vehicle. Cabin data is processed locally and is not transmitted to Tesla.

This feature is enabled by default. To disable, go to Controls > Safety > Child Left Alone Detection.”

Tesla later said that the feature is currently rolling out to mid-2023 and later Model 3 vehicles in Europe initially, while other models and regions will receive the update in the coming months.
