Asteroid 2024 YR4: Potential Threat to Earth Raises Concerns

In the quiet of Christmas Day 2024, astronomers made an unsettling discovery. An asteroid, 2024 YR4, about the size of a full-size football pitch, was spotted moving through space at an alarming speed. According to experts, the asteroid, between 40 and 100 meters in width, is traveling away from Earth at 38,000 mph. However, its orbit will bring it close to our planet around Christmas 2032, raising concerns about its potential to collide with Earth.

The European Space Agency (ESA) has raised the alarm about this asteroid, which they state has a 1.2% chance of striking Earth at 5:25 AM on Wednesday, December 22, 2032. This risk has made it the highest on the ESA’s “asteroid risk list,” a troubling distinction given that the second-highest risk asteroid poses only a 0.68% chance of impact. This news may be unsettling, but it’s important to remember that the threat, while real, is still quite small.

ESA scientists have rated the asteroid’s risk as level three on the Torino Impact Hazard Scale, which is the highest level for any asteroid currently being monitored. This scale measures the probability and severity of a possible collision, indicating that 2024 YR4’s proximity to Earth warrants serious attention. As a result, two international organizations, the International Asteroid Warning Network and the Space Mission Planning Advisory Group, have been activated to assess the situation and determine how to prevent disaster.

While the idea of an asteroid hitting Earth can seem like the stuff of Hollywood blockbusters, experts have devised ways to prevent a catastrophic event. In fact, NASA’s recent Dart mission demonstrated that a spacecraft can change an asteroid’s trajectory. The mission showed that flying into an asteroid can alter its path by more than previously expected. For an asteroid of this size, the use of a spacecraft, called a “kinetic impactor,” could be enough to nudge it off course. “A kinetic impactor, a spacecraft, will be a lot more precise [than a nuclear bomb] because you can select the mass, the velocity and the direction of the impact,” said Ian Carnelli, a planetary defense expert at the ESA, according to The Telegraph.

While the idea of using nuclear weapons to destroy or divert an asteroid is often portrayed in movies, such as Armageddon, the reality is far more complex. Nuclear explosions in space are restricted by international treaties, and the technology to use nuclear weapons on asteroids is untested. As Carnelli explains, “It is a lot more complex with a nuclear device, and that is before you get into the political discussion because nuclear explosions in space are banned by UN treaties.” The alternative, using a spacecraft to gently redirect an asteroid, has been proven as a more controllable and reliable method.

Should 2024 YR4 collide with Earth, the impact would cause significant damage. An asteroid of this size is expected to create a crater as large as the city of Manchester, potentially causing global devastation. Experts say that such an event occurs only once every 700,000 years, but if it were to happen, the effects would be catastrophic. The asteroid’s potential to bring about such destruction serves as a powerful reminder of the fragility of life on Earth and the need for preparedness and prayer.

While we await further analysis of the asteroid’s exact trajectory, it is important for us as a Catholic community to reflect on the potential fragility of human life and the role of faith in the face of uncertainty. In moments of crisis, we turn to prayer for peace and guidance, trusting in God’s providence and asking for His mercy. Whether the asteroid will ultimately hit Earth is still uncertain, but it serves as a timely reminder of the preciousness of life and the need for vigilance, prayer, and unity in times of global concern.

As we reflect on the possibility of a catastrophe, let us pray for the wisdom and courage of the scientists and engineers working to deflect this asteroid, and for the strength to face whatever may come, knowing that God holds our future in His hands.
