This page shows the results of the runs of NEOScan on the NEAs which have impacted the Earth a few hours after their discovery. Currently there are seven such asteroids, namely 2024BX1, 2023CX1, 2022WJ1, 2022EB5, 2019MO, 2018LA, 2014AA, and 2008TC3. Note that they also have a dedicated page in the Past Impactors Page of NEODyS, showing the results obtained with the Line Of Variations method.

Asteroid 2014AA
Asteroid 2014AA has been discovered by Richard Kowalski at the Catalina Sky Survey on the New Year's Eve of 2014. It was roughly 2–4 metres in diameter and struck the Earth on 2 January 2014. The object was discovered 21 hours before the impact, but it has just 7 observations bacause not recognised as a potential impactor given the atypical night in which it has been spotted.

Asteroid 2008TC3
Asteroid 2008TC3 has been discovered by Richard Kowalski at the Catalina Sky Survey on October 7, 2008. It was 4.1 metres in diameter and entered Earth's atmosphere on October 7, 2008. It exploded at an estimated 37 kilometres altitude above the Nubian Desert in Sudan.
The object was spotted 19 hours before the impact, and it is the first body to be observed and tracked prior to reaching the Earth. After the discovery, hundreds of astrometric observations have been submitted to the Minor Planet Center and these observations allowed the computation of the orbit and the prediction of the impact.
