the time.
But it would soon become one of the best-documented—and most baffling—UFO sightings of the 21st century. planetxnews Posted On June 10, 2020. To overcome this obstacle, the astronomers supplemented the TESS data from higher-resolution ground-based telescopes, including three run by amateur astronomers. The vast majority of NEAs pass by safely at much greater The white dwarf is the remnant of a sun-like star, greatly shrunken down to roughly the size of Earth, yet it retains half the sun's mass. That caused the planet to take on an exaggerated, oval orbit that passed very close to the now-shrunken white dwarf but also flung the planet very far away at the orbit's apex.Over eons, the gravitational interaction between the white dwarf and its planet slowly dispersed energy, ultimately guiding the planet into a tight, circular orbit that takes just one-and-a-half days to complete. With Matthias Schoenaerts, Géza Röhrig, Tawfeek Barhom, Aidan Turner. "It's really cool to see a small asteroid come by this close, because we can see the Earth's gravity dramatically bend its trajectory," said Paul Chodas, director of the Center for Near-Earth Object Studies (CNEOS) at NASA's Jet Propulsion Laboratory in Southern California.
"Once the glare was under control, in one night, they got much nicer and much cleaner data than we got with a month of observations from space," says Vanderburg.
These larger asteroids pose a much greater threat NASA's Planetary Defense Coordination Office. It's a pleasant surprise," says lead researcher Andrew Vanderburg, who recently joined the UW-Madison astronomy department as an assistant professor. Vanderburg completed the work while an independent NASA Sagan Fellow at the University of Texas at Austin.The researchers published their findings Sept. 16 in the journal,Vanderburg was originally drawn to studying white dwarfs—the remains of sun-sized,"What we ended up finding was that this was a.Ever since, Vanderburg has wondered if planets, especially large ones, could survive the journey in toward an aging star.By scanning data for thousands of white dwarf systems collected by TESS, the researchers spotted a star whose brightness dimmed by half about every one-and-a-half days, a sign that something big was passing in front of the star on a tight, lightning-fast orbit.

".A division of Caltech in Pasadena, JPL hosts CNEOS for NASA's Near-Earth Object Observations Program in The massive planet looms over its tiny star, which it circles every 34 hours thanks to an incredibly close orbit. NASA's Near-Earth Object Observations Program funds data processing for NEO detections.Asteroid 2020 QG enters the record books as the closest known nonimpacting asteroid; many very small asteroids impact our planet every year, but only a few have actually been But it was hard to interpret the data because the glare from a nearby star was interfering with TESS's measurements. the size of 2020 QG, but they are extremely hard to discover until they get size. While there have been hints of large planets orbiting close to white dwarfs in the past, the new findings are the clearest evidence yet that these bizarre pairings exist. "We've never seen evidence before of a planet coming in so close to a white dwarf and surviving. Previous models of white dwarf-planet interactions didn't seem to line up for this particular star system.The researchers ran new simulations that provided a potential answer to the mystery. But an SUV-size asteroid set the record this past weekend for coming The unique structure of white dwarf-planet systems provides an ideal opportunity to study the chemical signatures of orbiting. Live. The system, about 80 light years away, violates all common conventions about stars and planets. It began as a routine naval training exercise. A sky-scanning survey telescope funded by the National Science Foundation and NASA, the Zwicky Transient Facility is based at Caltech's Palomar Observatory in San Diego County. That confirmation highlights the diverse ways stellar systems can evolve and may give a glimpse at our own solar system's fate.
