Summary
NASA is closely watching an asteroid named Apophis, which will pass very close to Earth on April 13, 2029. This asteroid is large and will come closer to Earth than many satellites, but it does not pose any danger to our planet.
Key Facts
- Apophis is about 1,115 feet wide and 1,480 feet long.
- It will come within 20,000 miles of Earth’s surface in 2029.
- This distance is closer than many satellites that orbit Earth at about 22,236 miles.
- Such a close approach by a large asteroid happens only once every few thousand years.
- When first found in 2024, Apophis was thought to possibly hit Earth, but now NASA says there is no risk for at least 100 years.
- The asteroid will be affected by Earth's gravity, which may change its orbit and rotation.
- Scientists will use this event to study Apophis and learn more about asteroids near Earth.
- This is the first time humans have had the tools to observe an asteroid this close well in advance.
