NASA's DART Impact Actually Changed an Asteroid System's Orbit Around the Sun NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense. NASA’s DART (Double Asteroid Redirection Test) spacecraft changed the motion of an asteroid system in space, demonstrating that a kinetic impactor could be a viable way to deflect a near-Earth object if one ever threatened Earth. New findings show that when the spacecraft deliberately crashed into the asteroid moonlet Dimorphos in September 2022, the impact did more than alter the small body’s motion around its larger companion, Didymos. The collision also slightly changed the path that both asteroids follow around the Sun. Didymos and Dimorphos are gravitationally bound and circle a shared center of mass, forming what astronomers call a binary asteroid system. Because the two bodies are linked in this way, changing one affects the other. First Measurable Human Impact on a Solar Orbit According to a study published in the journal Science Advances, scientists carefully tracked the motion of the asteroid pair after the collision. They discovered that the system’s 770-day orbit around the Sun shifted by a fraction of a second following the DART impact. This marks the first time that a spacecraft built by humans...

Imagine if the asteroid had missed and dinosaurs were still running the planet.
Human history — and politics — would look very different.
Sometimes evolution takes strange turns.

Once deemed the riskiest asteroid ever observed, asteroid 2024 YR4's path is now clearer The possibility that a huge space rock — once deemed the riskiest asteroid ever observed — could hit the moon now appears to be off the table. Discovered at the end of December 2024, asteroid 2024 YR4 at first seemed a serious threat to Earth, with scientists estimating as much as a 3.1% chance of it impacting our planet on December 22, 2032. A series of observations from ground- and space-based telescopes quickly helped rule that out, but by June 2025, a new concern emerged: a 4.3% chance YR4 would slam into the moon instead. While Earth wouldn’t face any significant physical danger if the building-size asteroid struck the moon, researchers suggested that any astronauts or infrastructure on the lunar surface at the time could be at risk — as could satellites that we depend on to keep vital aspects of life, including navigation and communications, running smoothly. Astronomers didn’t expect to get a chance to better assess the risk of a YR4 lunar impact until the asteroid came back into view from Earth’s perspective in 2028. However, Dr. Andy Rivkin, planetary astronomer from the Johns Hopkins University’s Applied Physics Laboratory in Maryland, and Julien de Wit, associate professor of...

'The moon is safe': asteroid is not on collision course, scientists confirm Fears that a 100-metre-wide asteroid could be on course to collide with the moon appear to have been misplaced, according to new observations. Discovered in December 2024, asteroid 2024 YR4 was briefly considered the “most dangerous asteroid” in decades after scientists initially estimated it had a 3.1% chance of colliding with the Earth in 2032. Closer observations quickly ruled out a “city killer” scenario, but instead astronomers calculated there was a 4.3% chance that the moon lay in the path of impact. Although there would not be any danger to the Earth, lunar debris kicked up during a collision could interfere with satellites used for navigation and communications. But new observations appear to have eliminated this risk, showing that the asteroid will safely pass the moon at a distance of more than 20,000km (12,400 miles). “It would’ve been a very interesting science experiment but probably, given the small risk of debris, it wouldn’t be one we’d want to try out,” said Colin Snodgrass, a professor of planetary astronomy at the University of Edinburgh. “Some of us in the scientific community might be a little disappointed.” As the asteroid hurtled away from the Earth, fading from view, astronomers had not expected...

Asteroids May Have Laid the Groundwork for Life on Earth Here’s what you’ll learn when you read this story: One debate about the origin of life on Earth concerns whether it formed around deep-sea hydrothermal vents or in scars left behind by an asteroid impact. A new review article analyzes recent research regarding “impact generated hydrothermal vents” and finds that they might be the best candidates yet. Asteroids would’ve supplied the necessary raw materials, heat, and geologic plumbing to circulate prebiotic matter while also creating freshwater crater lakes that are even more conducive to supporting life. The origin of life has been debated by scientists, theologians, and philosophers since humans first developed the brain chemistry necessary to even ponder the question. However, in the last 50 years or so, the search for a resolution to that debate has gotten a bit more interesting. In February of 1977, during an expedition to the deep-ocean Galápagos Rift (located 250 miles north of the Galápagos islands), a team of scientists discovered the very first hydrothermal vent teeming with biological life. The expectation had been that the deep ocean would be mostly a desert as far as life was concerned, but this fateful expedition proved otherwise, and it posed a conundrum. Because the vent...

379E-415-Well Done Once every 1,435 days , a 780 foot diameter space rock that my Catalina Sky Survey teammate Carson Fuls discovered makes an annihilation defying close approach to our star. At it's nearest point to the Sun, Carson's well done space rock is traveling at an amazing 93 miles per second and receives 26 times the amount of solar radiation that heats the surface of the planet Mercury to 800F. After Carson first discovered his heat resistant space rock traveling towards it's next hot date with the Sun, it was observed by telescopes in New Mexico, Arizona, Hawaii, and England. These data allowed scientists at the Minor Planet Center to calculate it's orbit around the Sun, estimate it's size, and give it the name 2017 TC1. 2017 TC1 crosses the orbits of Mars, Earth, Venus, and Mercury and can come relatively close to Jupiter on it's extremely elliptical orbit about the Sun. It is possible that in the very distant past the giant planet Jupiter's pull on 2017 TC1 sent it on it's current path around the Sun. In September of 2021, 2017 TC1 will once again be bright enough for asteroid hunters to track as it makes another close approach to our Sun. At this time astronomers with be able to measure the pattern of colors that 2017 TC1 reflects which will reveal it's surface chemical composition. Until then we are left to wonder how it is possible for a space rock to survive on such a harrowing path.
