‘City killer' asteroid 2024 YR4 no longer a threat to Earth, scientists say
Scientists have finally given the all-clear to Earth from a
newly discovered asteroid

After two months of observations, scientists have almost fully ruled out any threat from the asteroid 2024 YR4, Nasa and the European Space Agency said Tuesday.
At one point, the odds of a strike in 2032 were as high as about 3 per cent and topped the world's asteroid-risk lists.
ESA has since lowered the odds to 0.001 per cent. Nasa has it down to 0.0017 per cent – meaning the asteroid will safely pass Earth in 2032 and there's no threat of impact for the next century.
Paul Chodas, who heads Nasa's Centre for Near Earth Objects Studies, said there was no chance the odds would rise at this point and that an impact in 2032 has been ruled out.

'That's the outcome we expected all along, although we couldn't be 100 per cent sure that it would happen,' he said in an email.
But there was still a 1.7 per cent chance that asteroid could hit the moon on December 22, 2032, according to Nasa. Chodas expects the odds of a moon strike will also fade.

Planet found orbiting tiny star puzzles scientists
Planet found orbiting tiny star puzzles scientists Astronomers discovered the planet when searching through low-mass red dwarfs observed by Nasa's Tess space telescope. Photo: AFP Astronomers announced on Wednesday that they had discovered a massive planet orbiting a tiny star, a bizarre pairing that has stumped scientists. Most of the stars across the Milky Way are small red dwarfs like TOI-6894, which has only 20 percent of the mass of our Sun. It had not been thought possible that such puny, weak stars could provide the conditions needed to form and host huge planets. But an international team of astronomers have detected the unmistakable signature of a gas giant planet orbiting the undersized TOI-6894, according to a study in the journal Nature Astronomy. This makes the star the smallest star yet known to host a gas giant. The planet has a slightly larger radius than Saturn, but only half its mass. It orbits its star in a little over three days. The astronomers discovered the planet when searching through more than 91,000 low-mass red dwarfs observed by Nasa's Tess space telescope. Its existence was then confirmed by ground-based telescopes, including Chile's Very Large Telescope. The James Webb space telescope is scheduled to turn its powerful gaze towards the planet in the next year, which could help uncover some more mysteries of this strange planet. (AFP)

Did China's Tiandu-1 satellite beat US competitors with critical Earth-moon orbit?
China's Tiandu-1 satellite has entered a critical fuel-efficient orbit that synchronises with the motion of the Earth and moon, but claims that it is the first spacecraft to achieve the feat have been challenged by US and Canadian experts. The 3:1 resonant orbit – in which Tiandu-1 completes three loops of the Earth for every circuit made by the moon – is seen as a breakthrough for lunar infrastructure, including a BeiDou-like guidance system that will be needed for interplanetary exploration. Developer Deep Space Exploration Laboratory said that 'the Tiandu-1 navigation test satellite successfully carried out a key manoeuvre at perigee [the point in orbit when it is closest to Earth] on May 22 and precisely transitioned into a 3:1 Earth-moon resonant orbit'. A Deep Space Exploration Laboratory schematic of the Tiandu-1 satellite taking part in a laser ranging experiment in April, before it was moved into the 3:1 resonance orbit. Credit: DSEL 'This made Tiandu-1 the first spacecraft to enter a round-trip 3:1 Earth-moon resonant trajectory,' according to a statement on the website of the laboratory based in Hefei, Anhui province in central China. 'Its flight data will provide support for advancing technologies such as orbit maintenance, control, and autonomous navigation in complex gravitational environments.' Experts in the US and Canada immediately challenged the claim, pointing to Nasa's 15-year-old Interstellar Boundary Explorer (IBEX) probe that entered a near-identical orbit in 2011, where it continues to operate. Jonathan McDowell, a Harvard astronomer and space historian, and Canada-based amateur stargazer Scott Tilley both said it was debatable whether Tiandu-1 could lay claim to the title, with the IBEX craft's achievement of near 3:1 resonance. 'Yes, indeed Tiandu-1 has entered a 3:1 resonance orbit. Whether it's the first is debatable…IBEX launched in 2008 uses a similar orbit,' Tilley said.
