An animation of an asteroid’s close approach to Earth has attracted a lot of views over the last few days, largely because of just how close it appears.
The animation, shared by Facebook page Cosmoknowledge on Sunday, shows asteroid 99942 Apophis’s path, culminating in its closest approach on April 13, 2029. To be clear, there is nothing to fear from this asteroid, which is predicted by NASA not to hit Earth in 2029, nor in another close approach in 2036. However, the animation is still what is known as a nailbiter.
In April 2029, Apophis is
It may sound close (in terms of space that is, not in terms of a jaunt) but astronomers are not concerned. In 2021, Apophis made a flyby of Earth, at which point astronomers made powerful radar observations in order to better define its orbit. Before that, NASA believed that it had a chance of impact later in the century, but the observations ruled that out.

Other animations, a little closer and from a different angle, are more reassuring. NASA’s
NASA is going to use the 2029 flyby to take a
