Question 1

What is DoomsdayWatch?

Accepted Answer

DoomsdayWatch is a free, real-time asteroid tracking dashboard that displays near-Earth object data from NASA's JPL (Jet Propulsion Laboratory). It features live radar visualization, threat level assessments, and AI-powered commentary.

Question 2

Where does the asteroid data come from?

Accepted Answer

All asteroid data comes directly from NASA's Near Earth Object Web Service (NeoWs) API, which provides information about asteroids tracked by NASA's Center for Near Earth Object Studies (CNEOS) at the Jet Propulsion Laboratory.

Question 3

How often is the asteroid data updated?

Accepted Answer

The asteroid data is fetched fresh from NASA's API each time you load the page or click the refresh button. NASA updates their asteroid tracking data continuously as new observations come in.

Question 4

What does "potentially hazardous asteroid" mean?

Accepted Answer

NASA classifies an asteroid as "potentially hazardous" if it has a minimum orbit intersection distance (MOID) of 0.05 AU or less and an absolute magnitude of 22 or brighter. This doesn't mean it will hit Earth, just that it warrants monitoring.

Question 5

Is DoomsdayWatch an official NASA website?

Accepted Answer

No, DoomsdayWatch is an independent project that uses publicly available NASA data. For official information about asteroid threats, please visit NASA's Center for Near Earth Object Studies (CNEOS) at cneos.jpl.nasa.gov.
