Introduction:
This week, Earth is set to witness a series of close encounters with five asteroids, ranging in size from house-sized to as large as a Fifa-accredited football stadium. While there’s no collision risk, the celestial spectacle has caught the attention of skywatchers. Here’s a comprehensive FAQ to shed light on this cosmic event.

1. What are the names and sizes of the five asteroids approaching Earth?

• The asteroids are Asteroid 2008 OS7 (890 feet), Asteroid 2024 AU4 (260 feet), Asteroid 2007 EG (size of an airplane), Asteroid 2024 BY (house-sized), and Asteroid 2003 BM4 (airplane-sized).

2. When will these asteroids pass by Earth?

• Asteroid 2024 AU4: Sunday, at a safe distance of 3.92 million miles.

3. How does NASA track these asteroids, and what is Asteroid Watch?

• NASA’s Jet Propulsion Laboratory (JPL) monitors these celestial bodies through its Asteroid Watch website. This platform provides real-time information about upcoming asteroid approaches, including size, distance, and potential impact risks.

4. Is there a collision risk with any of these asteroids?

• No, there is no collision risk associated with these asteroids. While some will pass relatively close in cosmic terms, they are not on a collision course with Earth.

5. What is the significance of the largest asteroid, 2008 OS7?

• Asteroid 2008 OS7, approximately 890 feet across, is the largest among the five. While it poses no collision threat, its proximity has garnered attention from skywatchers.

6. How does the size of these asteroids compare to familiar objects?

• The size comparison includes an asteroid the size of a Fifa-accredited football stadium (2008 OS7) to house-sized (2024 BY) and airplane-sized (2007 EG and 2003 BM4) asteroids.

7. What is NASA’s classification of potentially hazardous asteroids (PHAs)?

• PHAs are asteroids and comets larger than 500 feet that can come within 4.7 million miles of Earth. While most near-Earth objects (NEOs) pose no risk, PHAs warrant closer attention due to their size and proximity.

8. What is the ‘God of Chaos’ asteroid, Apophis?

• Apophis is a massive asteroid, about 370 yards across, often dubbed the ‘God of Chaos.’ NASA launched OSIRIS-APEX to study Apophis, which is expected to have a close flyby of Earth at 20,000 miles in 2029, marking the closest approach of an asteroid this size in recorded history.

Conclusion:
While Earth experiences close encounters with these asteroids, NASA assures that there is no imminent collision risk. The ongoing monitoring of near-Earth objects is part of NASA’s efforts to study and understand these celestial bodies for future planetary defense strategies. Skywatchers can enjoy this celestial spectacle without concerns of impact.
