There are some false reports doing the rounds of a very large asteroid, 2022 AP7, "certain" to strike Earth.
2022 AP7's orbit is well known 100 years into the future and it will not strike Earth or even make a close approach (atleast for a century.)

This doesn't mean it will strike in 101 years! Only that our #PlanetaryDefence experts calculate asteroid orbits for the next hundred years. Any asteroid with even a tiny chance of impact is added to ESA's #AsteroidRiskList, and becomes the focus of intense observations
New data improves our understanding of its orbit and reduces any uncertainties, after which point it usually becomes clear it will not strike and its removed from the list

The surprise close approach of asteroid '2019 OK' illustrates need for more eyes on the sky☄️🔭

Two key goals of ESA’s #PlanetaryDefence activities are, by 2030, Europe will be able to
1. Provide early warning for dangerous asteroids larger than 40 m in size, about three weeks in advance☄️

1. The planned #AIDA mission will be the first to test asteroid deflection. @NASA's #DART spacecraft will be crashed into asteroid #Didymoon, and ESA's #HeraMission will observe the effects. Find out more: esa.int/Our_Activities…
2. Explode asteroid: speaks for itself!💥
