A University of Hawaiʻi Institute for Astronomy (IfA) astronomer has revealed critical new findings linked to a large asteroid expected to pass extremely close to Earth. Dave Tholen and collaborators have announced the detection of Yarkovsky acceleration on the near-Earth asteroid Apophis. This acceleration arises from an extremely weak force on an object due to non-uniform thermal radiation. This force is particularly important for the asteroid Apophis, as it affects the probability of an Earth impact in 2068.

European Space Agency warns: China's Tiangong-1 space station 'will crash into Earth over Easter' possibly hitting populated areas- by Harry Pettit

| China's out of control space station Tiangong-1 to crash on earth |
The
agency's Space Debris Office has said Tiangong-1 will hit somewhere
across our planet's northern hemisphere between March 30 and April 2.
Previous
estimates suggested the rogue station, China's out of Cwhich is
carrying highly toxic chemicals, would enter Earth's orbit on April 3.
According
to experts tracking the station, it has the highest chance of crashing
along a narrow strip around latitudes of 43 degrees north and south.
'At no
time will a precise time/location prediction from ESA be possible,' the
agency's Space Debris Office, based in Darmstadt, Germany, said in a statement.
The doomed 8.5-tonne craft has been hurtling towards Earth since Chinese scientists lost control of it in 2016.
Experts believe most of Tiangong-1 will burn up upon reentry, but shards as large as 100kg (220lbs) could strike Earth.
Scientist
believe that even in 'high risk' areas, the chance of being struck by
Tiangong-1 debris is about one million times smaller than the odds of
winning the Powerball jack.
However, there is a chance parts of the station containing hazardous hydrazine could plummet into a highly-populated area.
