Asteroid fun facts in pics: NASA reveals all you need to know
Asteroid and Earth
1/5 Space is full of objects, out of which only a few have been discovered. Asteroids are some of these objects. If you are not aware about the dangerous objects called asteroids, here are some facts you should know. First, did you know that asteroids are sometimes called minor planets? Well, they are.

2/5 Differences between an Asteroid, Comet, Meteoroid, Meteor and Meteorite: According to the information provided by NASA, Asteroid is a relatively small, inactive, rocky body orbiting the Sun. Comet is a relatively small, at times active, object whose ice can vaporize in sunlight forming an atmosphere (coma) of dust and gas and, sometimes, a tail of dust and/or gas. Meteoroid is a small particle from a comet or asteroid orbiting the Sun. Meteor is the light phenomena which results when a meteoroid enters the Earth's atmosphere and vaporizes, in short, a shooting star. While, Meteorite is a meteoroid that survives its passage through the Earth's atmosphere and lands upon the Earth's surface. (NASA)

3/5 Asteroid: Size, frequency and impact- More than 100 tons of dust and sand sized particles are bombarded towards Earth everyday, according to NASA. While, about once a year, an automobile-sized asteroid hits Earth's atmosphere, creates an impressive fireball, and burns up before reaching the surface. Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area. Only once every few million years, an object large enough to threaten Earth's civilization comes along. Impact craters on Earth, the moon and other planetary bodies are evidence of these occurrences. Space rocks smaller than about 25 meters (about 82 feet) will most likely burn up as they enter the Earth's atmosphere and cause little or no damage. By comparison, asteroids that populate the main asteroid belt between Mars and Jupiter, and pose no threat to Earth, can be as big as 940 kilometers (about 583 miles) across. (NASA)

4/5 How is an Asteroid Orbit Calculated? An asteroid's orbit is computed by finding the elliptical path about the sun that best fits the available observations of the object. That is, the object's computed path about the sun is adjusted until the predictions of where the asteroid should have appeared in the sky at several observed times match the positions where the object was actually observed to be at those same times.

5/5 What is NASA doing to find and learn more about potentially hazardous asteroids and comets? NASA has established a Planetary Defense Coordination Office (PDCO), managed in the Planetary Science Division at NASA Headquarters in Washington, D.C. The PDCO ensures the early detection of potentially hazardous objects (PHOs) - asteroids and comets whose orbits are predicted to bring them within 0.05 Astronomical Units of Earth (5 million miles or 8 million kilometers) and of a size large enough to reach Earth's surface - that is, greater than approximately 30 to 50 meters. NASA tracks and characterizes these objects and issues warnings about potential impacts, providing timely and accurate information. NASA also leads the coordination of U.S. Government planning for response to an actual impact threat. (AFP)

NASA has warned that a massive asteroid is headed towards Earth. The asteroid is large enough to end all life and cause total annihilation on the planet if it makes a surface impact on Earth. However, chances of an ateroid strike are remote at the moment as it i likely to pass by Earth. Having aid that, it has still managed to cause panic among the space agencies due to the extremely close distance with which it will pass by Earth.

The Asteroid 2020 PT4 will just miss Earth on September 14, which is tomorrow at a distance of 7.1 million kilometers. It is travelling at a staggering speed of 39,024 kilometers per hour. The asteroid is nearly the size of a commercial aircraft with a width of nearly 120 feet. This asteroid does not pose any viable threat to Earth and will pass the planet safely though it was still classified as a potentially hazardous asteroid due to the close proximity of its encounter with Earth.

Asteroid 2020 PT4 is part of the Apollo group of asteroids. According to the-sky.org, this asteroid takes almost 734 days to complete one orbit of the Sun, during which its farthest distance from the Sun is 355 million kilometers and nearest distance is 122 million kilometers.

NASA currently has a NEO Observations Program in place to track, and characterize at least 90 percent of the NEOs that are 140 meters or larger in size. Most of the asteroids are observed with the help of the NEOWISE Project which repurposed NASA's Wide-field Infrared Survey Explorer to work as a survey telescope and scan the sky for Near-Earth Objects.

Did you know?

Until now, it was believed that water was already present on Earth when the first living beings came into existence. However, a recent study has made an astonishing discovery that puts this very thought into doubt. The study has revealed that water may have originated on an asteroid.

The study was conducted after collecting samples from an asteroid called Ryugu by the Japanese Hayabusa-2 space probe during a 6-year space mission.

The probe gathered 5.4 grams of dust and rock samples from the asteroid which scientists used to gather information on the origin of life.

"Volatile and organic-rich C-type asteroids may have been one of the main sources of Earth's water," the scientists said in the published paper.
