Good news from NASA: Earth is safe from the dangerous asteroid 99942 Apophis for the next 100 years. So if you'd put this on your apocalyptic bingo card, you'll need to print new ones.

Nasa has given Earth the all clear on the chances of an asteroid called Apophis hitting our planet any time in the next century, having worried space scientists for over 15 years.
The 340-metre (1,100ft) chunk of space rock hit the headlines in 2004 after its discovery led to some worrying forecasts about its orbit. It became a "poster child for hazardous asteroids", according to one Nasa expert.
It was supposed to come frighteningly close in 2029 and again in 2036. Nasa ruled out any chance of a strike during those two close approaches a while ago, but a potential 2068 collision still loomed.
In case you are keeping track:
Earth safe from Asteroid Armageddon for next 100 years
NASA tracks near-Earth objects (NEO) to calculate the risk of a catastrophic impact with an asteroid.
Born in the asteroid belt between Jupiter and Mars, Apophis is a 1,000-foot-wide chunk of rock, nickel and iron that wobbles around the Sun in just under an Earth year.
NASA became interested in the asteroid in 2004 when scientists noticed it seems to be wobbling closer and closer to Earth.
Rubble Pile 'Dust Bunny'-Like Asteroids Could Still Pose Threat To Earth
The strange binary Asteroid 65803 Didymos-Dimorphos could be held together like dust bunnies, says an international team of researchers that includes queen rock guitarist and astrophysicist Brian May.
The study, published in the journal Icarus , details how the same forces responsible for building dust bunnies under our beds may be responsible for holding the asteroid Didymos together, says the European space agency (ESA).
Based on the team's calculations, Didymos requires a surface cohesion of between 3 to 6 Pascals (the standard unit of pressure), and an internal 'bulk' cohesion of between roughly 11 to 17 Pascals, depending on particle arrangement and size distribution, says ESA.
NASA says monster ′Apophis′ asteroid no longer a threat | News | DW | 27.03.2021
US astronomers have confirmed the Earth is safe from a massive asteroid for at least 100 years. A close call had been originally estimated for 2068.
NASA said Friday that an asteroid 1,100 feet (340 meters) across poses no risk of hitting the Earth, according to new radar observations made earlier in March.
Discovered in 2004, "Apophis" had been thought of as one of the most "hazardous asteroids that could impact Earth," NASA said.
NASA: Earth safe from being whacked by asteroid
Apophis quickly gained notoriety as an asteroid that could pose a serious threat to Earth when astronomers predicted that it would come uncomfortably close in 2029. Thanks to additional observations of the near-Earth object (NEO), the risk of an impact in 2029 was later ruled out, as was the potential impact risk posed by another close approach in 2036. Until this month, however, a small chance of impact in 2068 still remained.
