But 2021 SM3 will be followed up just five days later by an even larger asteroid heading for Earth. Dubbed 1996 VB3, this asteroid's size ranges between 100 meters to a whopping 230 meters, taller than the height of San Francisco's iconic Golden Gate Bridge, and is set to fly past the Earth on October 20. This asteroid is set to pass even closer to the planet, around 3.2 million kilometers away, though it is still not predicted to impact the planet.

Luckily, NASA has estimated that the Earth is at no risk of being impacted by an asteroid within the next 100 years, though this notably only applies to asteroids coming from the "front," meaning towards Earth and the Sun. Asteroids coming from the "back," towards Earth away from the Sun, are still notoriously difficult to detect. On September 16, asteroid 2021 SG, ranging between 42 meters and 94 meters in size, flew past the Earth, and scientists never even knew it existed, let alone flying past the planet, until the next day.
