While a miss this close might sound alarming, the European Space Agency (ESA) claims there was never any serious danger. Based on its estimated size, 2025 TF would have most likely burned up or exploded in the atmosphere rather than slamming into the surface. ESA said in a statement: 'Objects of this size pose no significant danger. 'They can produce fireballs if they strike Earth's atmosphere, and may result in the discovery of small meteorites on the ground.'
For the last 4.5 billion years our planet has had a reliable celestial companion - the moon. Its orbit around the Earth has a profound effect on life here, from influencing the tides to stabilising our seasons. But astronomers have now discovered another sidekick that may have been following our planet around for some time. Experts at the Pan-STARRS observatory in Hawaii have spotted a quasi-moon, called '2025 PN7', that has been tagging along after Earth since the 1960s.
