Retired NASA Engineer: ‘We’ve Been Tracking This Object Since 2019’

Unveiling the Mystery: The Object Tracked by NASA Since 2019

Six months ago, a retired NASA engineer sat down for an interview, speaking carefully and with measured words. Then, he said something that immediately caught the attention of everyone in the room: “We’ve been tracking an object since 2019.” Not a comet with a name you’d recognize, nor an asteroid listed in public catalogs, but an object that had been observed continuously by NASA across multiple systems for over five years.

The engineer didn’t elaborate further on camera; he simply smiled and moved on. But that brief statement opened a door, one that would lead to a fascinating, ongoing investigation. Because when you track something for five years in deep space, it’s not casual—it means you’re watching something that matters. Something that doesn’t fit the usual patterns.

The Evidence and the Technology Behind the Mystery

Tonight, we’ll walk you through the data and evidence that help us understand this mysterious object. We’ll look at real orbital data, NASA’s tracking capabilities, and documented instances of objects that have perplexed scientists between 2019 and now. This isn’t about wild speculation or conspiracy theories—this is based on hard evidence and logic.

By the end of this, you’ll understand why tracking an object for five years isn’t routine, why it was kept quiet, and what this could mean for our understanding of space. This isn’t just about aliens; it’s about something far stranger. It’s about objects that slip into our solar system, ones that don’t behave the way we expect them to. Objects that make NASA engineers stop and question their own math. The ones that raise alarms in tracking systems few people even know exist.

Why This Object Matters

NASA tracks tens of thousands of objects—asteroids, comets, debris, satellites. The objects that get names and press releases represent a tiny fraction of those tracked. The rest are monitored quietly in databases by automated systems and small teams of specialists. But sometimes, an object raises questions, and when those questions persist for years, it becomes clear that something unusual is going on.

So, why has this object been tracked for so long? Let’s go back to 2019. The object first appeared as a faint blip in survey data. One or two observations were enough to suggest it was worth monitoring, but not enough to confirm anything strange. The data sat there, waiting. Then, things changed.

In 2023, advancements in artificial intelligence (AI) scanning tools allowed NASA to comb through older astronomical images in search of patterns that human observers might have missed. These AI systems discovered something—multiple hits across different observation windows, spanning years. The object was present in 2019 data, and it reappeared in 2020 and later years. The AI was matching sensor data from different times and finding the same object.

The Convergence of Different Data Sources

By 2023, NASA’s space force had also upgraded its cis-lunar monitoring. New radar installations now allowed detection of fainter objects in the region between the Earth and the moon, objects that had been invisible to previous systems. With these upgraded capabilities, both civilian telescopes and military radar independently began tracking the same object. This convergence of data streams—across different detection systems—was rare and raised eyebrows among scientists. Objects that show up consistently across such diverse monitoring systems are not random noise. They are real, and they matter.

Three Possible Hypotheses

With the data coming in from multiple sources, teams at NASA started testing three possible hypotheses. Each one fits some aspects of the data, but none fits perfectly. Here are the three possibilities:

1. Hypothesis A: An Interstellar Visitor
   The first hypothesis suggests the object is an interstellar visitor—either a comet or asteroid from another star system. However, unlike other interstellar objects like Borisov, which blazed brightly with a visible coma, this object has remained dim, with minimal outgassing and almost no visible activity.

2. Hypothesis B: A Long-Lost Rocket Stage or Probe
   Another theory posits that the object is a long-lost piece of hardware—a rocket stage or probe from the 1960s or 1970s, a relic from decades ago that entered solar orbit and is now returning. NASA has documented similar cases, such as the 2020 SO object, which turned out to be an old booster from 1966.

3. Hypothesis C: A Captured Asteroid
   The third hypothesis suggests the object could be a small asteroid captured by Earth’s gravity, temporarily orbiting between Earth and the moon. These “mini-moons” are small, often just a few meters across, and they tend to orbit for months or years before escaping. If this object was captured in 2019, it could still be orbiting the Earth in an unstable orbit.

Testing the Hypotheses

Each of these possibilities predicts different behavior and orbital characteristics, and the teams tracking the object have been testing these predictions. They aren’t working on hunches or gut feelings—they’re following the math, comparing what the models say should happen with what is actually happening. When the two diverge, it can tell you something important.

The Subtle Nudge: Sunlight Pressure

One of the key pieces of data pointing toward the interstellar visitor hypothesis is the subtle but steady nudge the object has received from sunlight. Sunlight can exert pressure on objects in space, pushing them slightly off course. For large, heavy objects, this has little effect. But for smaller, lighter objects, it can cause noticeable changes in their trajectory. The 2020 rocket booster, for example, was pushed by sunlight because it was hollow and had a large surface area.

The 2019 object exhibits a similar subtle push from sunlight. It’s not a dramatic, unpredictable nudge like the jets of gas you’d expect from a comet, but a steady, predictable push. This suggests the object may be low-density, potentially hollow or thin—possibly even artificial. However, this remains speculative, as the evidence is not yet strong enough to confirm anything.

The Rotation: Clues About the Object’s Nature

Another clue comes from the object’s rotation. As objects in space rotate, they reflect sunlight in a pattern—brighter when a surface faces the Sun, dimmer when it doesn’t. The rotation period of the 2019 object is slow, around 7 to 8 hours, which is longer than most asteroids. This smooth, stable rotation suggests the object may be natural, or it could be inert hardware. Active spacecraft or comets show irregularities in their rotation due to control maneuvers or outgassing. This object doesn’t show such erratic behavior.

The Spectral Data: What’s Inside the Object?

Spectral data, which breaks down the light reflected from the object, reveals further insights. Different materials absorb and reflect light in distinct ways. When sunlight hits the object, it reflects in certain wavelengths that can tell us about its composition. Early spectral readings of the 2019 object suggest that it’s featureless—there are no strong signs of ice or paint. This suggests it’s either a very dark carbonaceous object or it has been weathered over time.

Interestingly, the object doesn’t show the obvious signs of human-made hardware, such as titanium dioxide or aluminum oxide, which are found in spacecraft coatings. This weakens the hardware hypothesis but doesn’t rule it out completely. It also doesn’t show the clear signs of a comet, like a visible coma or outgassing jets. This leaves us with a smaller set of possibilities.

Why It Matters: Implications for Planetary Defense

So why should we care about an object tracked for five years, faint and distant as it is? Because every unknown object is a blind spot in our planetary defense systems. If something dangerous were to approach Earth, we need to be able to identify it quickly, understand its orbit, and calculate its impact probability. Lingering uncertainties can cost valuable time—time we might not have.

Interstellar objects, once thought to be rare, may now be more common. This object could be the first of many. If we’re not prepared, these objects could pose risks to satellites, spacecraft, and even astronauts. This is why better tracking systems are crucial. If we can identify these objects in advance, we can mitigate potential risks.

The Road Ahead: What’s Next?

As the investigation continues, more data will be gathered to confirm or reject the three hypotheses. Spectral observations, radar campaigns, and further analysis of the light curve will help narrow down the possibilities. A potential interceptor mission has already been proposed, where a spacecraft could fly through the object’s trail and collect samples for analysis.

Whether the object is an interstellar visitor, a long-lost rocket, or a captured asteroid, we are closer than ever to understanding its true nature. The investigation is ongoing, and as more data arrives, the mystery will be solved. The key is in the details, and NASA is following the evidence wherever it leads.
