  • Are comets and asteroids a threat to our world?

    Comets and asteroids, as well as space debris, are closely monitored.

    NASA's Planetary Defense Coordination Office (PDCO) is responsible for ensuring the early detection of potentially hazardous objects – asteroids and comets whose orbits are predicted to bring them within 0.05 astronomical units of Earth, and that are large enough (30 to 50 metres) to cause significant damage on Earth.

    More information on comets and asteroids and on the PDCO.

  • Why is Mars red?

    Mars is known as the "red planet" due to its reddish hue caused by oxidized iron (or rust) on the planet's surface. You can learn more about Mars and Mars exploration on our website.
