Did you know that a stadium-sized asteroid is set to pass near Earth? According to Nasa, the 2024 ON asteroid, which measures approximately 290 metres (950 feet) across, will come within 1 million kilometers of our planet this Tuesday. This significant event underscores the importance of monitoring near-Earth objects (NEOs) to ensure our safety and understand the dynamics of our solar system.
This asteroid last passed by Earth in 2013, and it is expected to return in 2035. Such close encounters remind us of the vastness of space and the potential threats that exist beyond our atmosphere. The data collected by Nasa’s Jet Propulsion Laboratory helps scientists track these objects and predict their trajectories, which is crucial for planetary defense.
First detected by Nasa’s Near-Earth Object Observations Program, the 2024 ON is currently being monitored by the Virtual Telescope Project. On September 9th, it was observed moving at an impressive speed of around 40,000 kilometers per hour. While it poses no immediate threat to Earth, even a slight change in its trajectory could lead to significant consequences in the future.
Understanding the 2024 ON Asteroid
The 2024 ON asteroid is a remarkable celestial body that has garnered attention due to its size and proximity. At 290 meters in diameter, it is considerably larger than most asteroids that pass near Earth. Its sheer size makes it 99% larger than any other near-Earth objects, though it won't be visible to the naked eye during its closest approach.
As it reaches a minimum distance of 2.6 times the average lunar distance, the asteroid is not considered a risk to our planet on its current trajectory. However, space experts emphasize that even a minor deviation could change its path significantly, highlighting the need for ongoing observation and study.
Skywatching Opportunities
Interestingly, the same day that 2024 ON makes its closest approach, skywatchers will have the chance to witness a rare celestial event. A partial lunar eclipse will coincide with a supermoon full Moon, providing an exciting opportunity for stargazers. This event will be visible across Europe and Africa, with potential sightings in parts of North and South America and Asia.
Later in the month, another smaller asteroid, the 2024 PT5, will enter Earth's orbit and act as a temporary “mini moon.” This asteroid, measuring only 10 meters across, has historical significance as it once formed part of the Moon. It will stay within our orbit from September 29 until November 25, adding to the month’s exciting astronomical events.
