Mountain-sized asteroid to make a close approach to Earth today at 93,000 kmph
The approach of 2011 UL21 is a reminder of the unpredictable
nature of our solar system and the importance of monitoring near-Earth objects
(NOs). The European Space Agency (ESA) has been keeping a close eye on this
asteroid, and their observations confirm that it will safely pass by Earth
without incident.
Astronomers and space enthusiasts around the globe are
gearing up to observe this event. The Virtual Telescope Project (VTP), led by
astrophysicist Gianluca Masi, will provide a free livestream of the asteroid's
approach, sharing views from the Bellatrix Astronomical Observatory in Ceccano,
Italy. Masi stated, "It's probably one of the ten biggest asteroids to
pass within 4.7 million miles of our planet since 1900." He also noted
that while any potential impact from 2011 UL21 would be less extreme than
historic collisions, it still has the potential to cause damage on a
continental scale.
The close encounter with 2011 UL21 is scheduled to occur
after 4 p.m. ET on June 27, 2024. The asteroid will zip past our planet at a
speed of around 58,000 mph (93,000 km/h), showcasing the incredible velocities
at which these celestial bodies travel through space.
The significance of this event extends beyond the spectacle
of the asteroid's approach. It highlights the ongoing efforts in planetary
defense and the need for continued vigilance in tracking asteroids that could
pose a threat to Earth. While 2011 UL21 is not a danger, it serves as a
practice target for astronomers to refine their tracking and prediction
capabilities. This event also contributes to our understanding of the
composition and behavior of asteroids. Each close approach provides valuable
data that can be used to study the physical properties of these
space rocks, including their size, shape, and surface
features.
The passage of 2011 UL21 is a cosmic event that will be observed with great interest by the scientific community and the public alike. It is a reminder of the ever-present, albeit distant, neighbors that share our solar system and the importance of keeping a watchful eye on the sky.
