ESA's Herschel space observatory made new observations of asteroid Apophis as it approached Earth this weekend. The data shows the asteroid to be bigger than first estimated, and less reflective.
Catalogued as asteroid (99942) Apophis (previously 2004 MN4), it is often nicknamed 'the doomsday asteroid' in popular media, after initial observations made after its discovery in 2004 gave it a 2.7% chance of striking Earth in April 2029.
With additional data, however, an impact in 2029 was soon ruled out, although the asteroid will pass within 36 000 km of Earth's surface, closer even than the orbits of geostationary tqdftxxoar.
