Asteroid is identified as the fourth most common Earth impact and could hit the planet in less than 65 years.
- ESA has added asteroid 2019 SU3 to its long risk list.
- Asteroid is the fourth most "endangered" 1:15 scale chance to hit Earth
- It has an estimated diameter of 46 feet and could be hit on September 16, 2084
- However, experts say they do is not large enough to cause a major impact event
The European Space Agency (ESA) has added a new asteroid to the list of risks that could hit Earth in 65 years.
Identifying SU3 in 2019, this celestial body has an estimated diameter of 46 feet and is listed as the fourth most dangerous asteroid that threatens to hit our planet.
The ESA noted that a strike could occur on September 16, 2084, and there is a 152 chance of collision – but experts said it was not large enough to trigger a major impact event.

ESA has included a new asteroid (image archive) in the risk list that could hit Earth in less than 70 years. Identified as SU3 2019, this celestial body has an estimated diameter of 46 feet and is the fourth most dangerous asteroid that threatens our planet.
The Risk List is a catalog of all objects found to have a non-zero impact probability
Each entry contains details of the Earth's approach that presents the highest impact risk and includes an estimated impact date, the impact probability, and the size and speed of the asteroid ,
And ESA added SU3 based on this data in 2019. It was collected, as reported by the International Business Times for the first time, on the likelihood that it will hit Earth.
It is also listed in the agency's priority list so that experts can closely monitor the asteroid's path.
The ESA noted that the impact could occur on September 16, 2084 is one of 152 collision probabilities – but experts said they were not large enough to trigger a major impact event (picture in stock).
The asteroid has been on the risk list for about 12 days, according to the agency. ESA noted that the asteroid may hit Earth on September 16, 2084, and probably at a distance of only 0.00079 astronomical units or less heading for Earth is about 73,435 miles away.
Because it will be so close to Earth, experts who are tired could send it directly to our planet through a slight push by the gravitational pull of neighboring planets.
The agency also found that 2019 SU3 is an Apollo asteroid, part of a group of asteroids. It was discovered in the 1930s and has a very broad orbit around our planet. It was found to intersect with Earth orbit.
It has also been found that it passes into the orbits of Venus, Mercury and Earth Mars, from there could emanate the deadly attraction.
WHAT COULD WE DO TO STOP AN ASTEROID COLLIDING WITH THE EARTH?
Currently, NASA would not be able to distract an asteroid when it heads to Earth, but it could mitigate the impact and take action to protect lives and property.
This would include evacuating the impact area and moving the key infrastructure.
Find out about the orbit, size, shape, mass, composition and rotational dynamics Experts determine the severity of a possible impact.
But the key to mitigation is identifying a potential threat as early as possible.
NASA is currently developing a refrigerator-sized spacecraft capable of preventing asteroids from colliding with Earth. A test with a small, non-threatening asteroid is scheduled for 2024.
This is the first mission to demonstrate an asteroid deflection technique for planetary defense.
The Double Asteroid Redirection Test (DART) would use what is known as a kinetic impactor technique in which the asteroid is struck to shift its orbit.
The impact would change the speed of a threatening asteroid by a small fraction of its overall speed over time, leading to a large shift of the asteroid's path away from Earth.
However, the ESA warned that "by the time it reaches the Earth's proximity, it could already be on a direct collision course with the planet."
It is believed that the asteroid is not large enough to cause a major impact event when it hits the earth.
Just last month, the agency found that 878 asteroids are threatened with collision in the next 100 years and explained that even a small asteroid could lead to "serious devastation". To reduce the risk of collision, ESA and several other groups have joined forces to search for asteroids.
