NASA has released a plot of every potential dangerous asteroid that could potentially hit Earth.

The map, titled "Potentially Hazardous Asteroids," was released on August 2 in a post on the Planetary Photojournal and it shows the orbital paths of over 1,400 asteroids known to be heading towards our planet.

"These are the asteroids considered hazardous because they are fairly large (at least 460 feet or 140 meters in size), and because they follow orbits that pass close to the Earth's orbit (within 4.7 million miles or 7.5 million kilometers)," NASA officials explained in the image description.

NASA officials explained that "being classified as a PHA does not mean that an asteroid will impact the Earth."

"None of these PHAs is a worrisome threat over the next 100 years. By continuing to observe and track these asteroids, their orbits can be refined and more precise predictions made of their future close approaches and impact probabilities," NASA said.

NASA's Jet Propulsion Laboratory looks to find and share the latest developments regarding asteroid discoveries and potential collisions through their Asteroid Watch project.
