Sentinels of the Sky: Asteroids to Watch in the Future
Thanks to advancements in astronomy, we now know of numerous asteroids whose orbits bring them close to Earth. These are classified as Near-Earth Objects (NEOs), and within this group, Potentially Hazardous Asteroids (PHAs) are those requiring the closest monitoring.

NEOWISE
NASA's WISE (Wide-field Infrared Survey Explorer) spacecraft was an infrared-wavelength astronomical space telescope active from December 2009 to February 2011. In 2013 the spacecraft was assigned a new mission as NEOWISE, to help find near-Earth asteroids and comets.

André's Asteroid Adventure

Act 1
The Alert
André, a 10-year-old boy from Honduras, was scrolling through social media when a dramatic video appeared on his screen titled “An asteroid about to impact on Earth.” The comments below called it fake news, but André couldn’t help feeling a little worried. Wanting to know the truth, he decided to check NASA’s official social media page.

Act 2
The Official Source
As he scrolled, he found a clear post from NASA denying the rumor. The post explained that the asteroid’s path would safely miss Earth by millions of kilometers. Feeling relieved, André set aside his iPad and gazed out the window, his thoughts drifting.

Act 3
The What If...
He began to imagine different scenarios. "what if the asteroid had landed in the ocean or hit a city?" His curiosity grew stronger as he wondered how asteroid impacts really worked. Instead of fear, he now felt fascinated by space and its mysteries.

Act 4
The Simulation Tool
Searching online, André discovered a program called “Impactor-2025 Simulator.” The colorful design, full of buttons and maps of Earth, drew him in instantly. Excited, he started experimenting with different scenarios, turning his earlier worry into a spark of curiosity and a love for discovery.
