The chances have plummeted that a newly-discovered asteroid with the potential to wipe out a city will hit Earth on Valentine's Day 2046, the European Space Agency said on Tuesday.
The asteroid, which is named 2023 DW and is estimated to be around the size of a 50-meter Olympic swimming pool, was first spotted by a small Chilean observatory on February 26.
However Richard Moissl, the head of the ESA's planetary defense office, told AFP on Tuesday that overnight the probability fell to one in 1,584. This is because new observations shrink the"uncertainty region" where the asteroid will travel to on its closest point to Earth, he said. "The resulting explosion flattened trees over an area of about 2,000 square kilometers," Farnocchia said. London covers an area of around 1,600 square kilometers.
The asteroid, which is orbiting the Sun, came around nine million kilometers from Earth during its most recent closest approach on February 18—a week before it was discovered. Last year, NASA's DART spacecraft deliberately slammed into the pyramid-sized asteroid Dimorphos, significantly knocking it off course in the first such test of our planetary defenses.

Frontiers | Pancosmorio (world limit) theory of the sustainability of human migration and settlement in spaceIt seems to be an accepted assumption that human migration into space is inevitable. Humans are a species of Earth. We are connected to Earth through evolution. We are also connected to space; our bodies contain heavy elements generated by fusion in the cores of stars. What does this evolutionary connection of humans to a star and a planet mean for their ability to inhabit space? This paper combines 100 years of research and scientific development of a theory of ecological thermodynamics with classical mechanics theory and analytical models of self-restoring heat engines to explain how the Sun and Earth have evolved into islands of order in the entropy of space. An explanation is provided regarding how naturally occurring conservative force fields engage a diversity of natural resources in semi-reversible cycles that build a high-exergy ecosphere. The science and evidence suggest that the ability to establish a human settlement in space without the self-restoring order, capacity, and organization of Earth will ultimately lead to settlement failure. Supply chains would disappear, market resources would be depleted, advancement in human pursuits would be disrupted, social and governance systems would falter or collapse, human population numbers would decline, genetic diversity in the human genome would be lost, average human individual biomass would decrease, and human knowledge and understanding would be forgotten. What does it mean to have a location in space outside of Earth be “like Earth?” The results of research are presented as a pancosmorio theory of human sustainability that is developed using the scientific philosophy methodology of abductive reasoning. Four analytical models of space ecosphere sustainability and five hypotheses with proposed tests for falsifiability are provided, including a theorem that suggests a limit to human expansion into space. A new quantitative method of human sustainability is developed from theories of network ecology, providing
