NASA’s TESS Discovers Fastest Disintegrating Planet Ever Seen
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have identified the fastest disintegrating planet ever observed. This crumbling world, named BD+05 4868 Ab, is losing a ”moon’s worth” of matter every million years due to intense bombardment from its host star. Eventually, it will vanish entirely.
Located approximately 141 light-years away, BD+05 4868 Ab orbits the star BD+05 4868 A, making it the closest disintegrating exoplanet ever discovered. While its fate is grim, this exoplanet offers a unique opportunity for scientists to study the interiors of terrestrial worlds, which are typically hidden from view.Two teams of astronomers, including the MIT researchers who discovered the planet, are now collaborating to observe BD+05 4868 Ab using the James Webb Space Telescope (JWST). The Penn State University team, joining the effort, brings expertise from their recent study of another disintegrating exoplanet, K2-22b, located 801 light-years from earth.
“These planets are literally spilling their guts into space for us, and with JWST, we finally have the means to study their composition and see what planets orbiting othre stars are really made of,” said Nick Tusay, leader of the Penn State team and a researcher at the university’s Center for Exoplanets and Habitable Worlds.
The findings were presented at the 245th meeting of the American Astronomical Society in national Harbor, Maryland, on January 17, 2025. This discovery highlights the potential of TESS and JWST to uncover the secrets of distant worlds, even as they crumble into oblivion.

For centuries, understanding the interiors of planets in our solar system has been a monumental challenge. With limited access to Earth’s mantle and no direct samples from Mercury,Venus,or Mars,scientists have long relied on indirect methods to study planetary compositions. But now, thanks to groundbreaking research by teams from MIT and Penn State, astronomers are unlocking the secrets of distant exoplanets—hundreds of light-years away—by studying their disintegrating interiors.
“It’s a remarkable and fortuitous opportunity to understand terrestrial planet interiors,” said Jason Wright, a member of the Penn state team, in a statement. “Here we have found planets that are sending their interiors into space and backlighting them for us to study with our spectrographs.”
The Transit Method: A Window Into Alien Worlds
Both teams relied on the transit method, a technique that detects exoplanets as they pass in front of their host stars, causing a slight dip in starlight. this method has already been instrumental in discovering thousands of exoplanets, cataloged in NASA’s exoplanet archive. But the real magic happens when starlight filters through a planet’s atmosphere or surrounding debris, leaving behind a unique chemical fingerprint.
This process,known as spectroscopy,allows astronomers to decode the composition of a planet’s atmosphere or even its disintegrating surface. “When the planet’s insides are on the outside, spectroscopy offers a clever way to see within terrestrial worlds,” Wright explained.
Ultra-Short-Period Planets: Worlds on the Brink
The exoplanets under scrutiny are no ordinary worlds. These ultra-short-period planets orbit their stars in mere hours, placing them perilously close to their host stars. The intense heat and gravitational forces cause these planets to literally fall apart, ejecting their interiors into space.
This disintegration creates a trail of debris that backlights the star, providing a rare opportunity for astronomers to study the composition of these distant worlds.By analyzing the light that passes through this debris, researchers can identify the elements present, offering clues about the planet’s internal structure.

Studying these disintegrating exoplanets not only sheds light on their own compositions but also offers a unique viewpoint on the formation and evolution of terrestrial planets. By comparing these distant worlds to planets in our solar system, scientists can refine their understanding of planetary interiors and the processes that shape them.
As Wright aptly put it, “We have only limited sampling of Earth’s mantle, and no access to that of Mercury, Venus, or Mars—but here we have found planets hundreds of light-years away that are sending their interiors into space and backlighting them for us to study.”
The Future of exoplanet research
The discoveries made by the MIT and Penn State teams mark a significant leap forward in exoplanet research. As technology advances and more powerful telescopes come online, astronomers will be able to study even more distant and exotic worlds, unraveling the mysteries of their interiors and atmospheres.
For now, these disintegrating planets serve as cosmic laboratories, offering a rare glimpse into the building blocks of terrestrial worlds. And as we continue to explore the universe, each new discovery brings us closer to understanding our place in the cosmos.

The Mysterious World of disintegrating Planets: A Glimpse into BD+05 4868 Ab
In the vast expanse of the universe, some planets live fast and die young. Among these are the enigmatic ultra-short period planets (USPs), which orbit their stars in mere hours. These celestial bodies are so close to their host stars that they are literally falling apart, leaving behind trails of dust and gas that captivate astronomers. Recently, a team of researchers discovered one such disintegrating planet, BD+05 4868 Ab, which boasts the most prominent dust tails ever observed.
What Are Ultra-Short Period Planets?
Ultra-short period planets are a rare breed of exoplanets that complete an orbit around their stars in less than 24 hours. These planets are subjected to extreme heat and gravitational forces, causing their surfaces to erode and disintegrate over time. Only a tiny fraction of these planets are hot enough and have low enough surface gravity to disintegrate in a way that can be detected by telescopes on Earth.
Before the discovery of BD+05 4868 Ab, only three disintegrating planets were known among the over 6,000 entries in NASA’s exoplanet catalog. This makes the discovery of BD+05 4868 Ab a significant milestone in the study of these fleeting worlds.
The Dramatic Disintegration of BD+05 4868 Ab
BD+05 4868 Ab is no ordinary planet. As it orbits its star, material blasts away from its surface in a chaotic process that alters the strength of the transit signal each time it crosses the face of its star. This dynamic disintegration creates a trail of dust and gas that stretches an astonishing 5.6 million miles (9 million kilometers)—encircling more than half of the planet’s orbit.Marc Hon,the MIT team leader,described the phenomenon in a statement: “The disintegrating planet orbiting BD+05 4868 A has the most prominent dust tails to date. The dust tails emanating from the rapidly evaporating planet are gigantic.”
The process is reminiscent of a comet passing close to the sun, leaving behind a glowing tail of debris. However, unlike comets, which are icy bodies, disintegrating planets are rocky worlds being torn apart by the intense heat and gravitational forces of their host stars.
Why Are Disintegrating Planets So Rare?
Disintegrating planets are rare because they must meet very specific conditions to be detectable. They need to be extremely hot, have low surface gravity, and be close enough to their stars to experience significant erosion.Additionally,the dust and gas trails they leave behind must be large enough to be observed from earth.
The discovery of BD+05 4868 Ab provides astronomers with a unique opportunity to study the final stages of a planet’s life. By analyzing the composition and behavior of its dust tails,scientists can gain insights into the internal structure and composition of these planets.
