Why Mumbai Is Being Linked To 'City Killer' Asteroid: All You Need To Know

Asteroid 2024 YR4 is being keenly watched by astronomers since its discovery in December last year. Dubbed “city killer”, the space rock now has an estimated 1.5 per cent (or 1 in 67) chance of striking our planet during a close flyby on December 22, 2032. Since the chance of the asteroid hitting our planet is above the threshold level of one per cent, space agencies across the world, including NASA, have been closely monitoring its trajectory.

Astronomers have posted simulation of the expected impact corridor of 2924 YR4. It is based on NASA’s assessment, as reported by Scientific American, and stretches from the eastern Pacific Ocean to South Asia. The area covers massive population centres, such as Bogota, Colombia, Lagos, Nigeria and Mumbai.

There’s also a very small chance that the incoming space rock could strike the moon.

The asteroid is believed to be 130 to 300 feet wide – about the size of a large office building. If there is a collision with Earth, whether the asteroid breaks apart in our planet’s skies or punches a crater into the surface, the immediate effects could resemble a detonating hydrogen bomb, unleashing enough localised devastation to destroy any metropolis in the way.

But the odds are reducing every day. Scientists believe it will reduce to zero, like what happened with Apophis. “At some point in the next months to few years, the probability will go to zero,” the New York Post quoted Bruce Betts, chief scientist for the nonprofit Planetary Society, as saying.

Still, astronomers are not leaving anything to chance. NASA is coordinating with other space agencies like the China National Space Administration (CNSA), the Russian space agency Roscosmos, and the European Space Agency (ESA) to map out the asteroid’s path. A team of astronomers will use NASA’s James Webb Space Telescope to further check estimates of the asteroid’s size and trajectory in early March – and again in early May, just before it dwindles from view (until its orbit brings it close to Earth again in 2028).

This Asteroid Could Hit Earth In 2032, Threatening To Wipe Out A City

NASA scientists have found an asteroid named 2024 YR4, which might collide with Earth in 2032, posing a 1-in-83 chance of impact. The asteroid, measuring around 130 to 300 feet across, is too small to threaten the extinction of humankind, but experts warn that it could cause massive destruction if it hits a major city. The impact would unleash an energy equivalent to 8 megatons of TNT-more than 500 times the power of the atomic bomb that obliterated Hiroshima, Japan.

According to NASA, the scientific analysis of a near-Earth asteroid, designated 2024 YR4, indicates it has a more than 1% chance of impacting Earth on December 22, 2032-which also means there is about a 99% chance this asteroid will not impact. Such initial analysis will change over time as more observations are gathered. Currently, no other known large asteroids have an impact probability above 1%.

Asteroid 2024 YR4 was first reported on December 27, 2024, to the Minor Planet Centre-the international clearinghouse for small-body positional measurements-by the NASA-funded Asteroid Terrestrial-impact Last Alert System station in Chile. The asteroid, which is estimated to be about 130 to 300 feet wide, caught astronomers’ attention when it rose on the NASA automated Sentry risk list on December 31, 2024. The Sentry list includes any known near-Earth asteroids that have a non-zero probability of impacting Earth in the future.

There have been several objects in the past that have risen on the risk list and eventually dropped off as more data have come in. New observations may result in reassignment of this asteroid to 0 as more data come in.
