We are experiencing an asteroid passing once again. An asteroid which is called 52768 (1998 OR2), that first spotted in the year 1998 will pass again on 29th April 2020. Fortunately, it will not strike Earth but will pass within 3,908,79, moving at 19,461 miles per hour.
Asteroid flyby is expected to occur at 5:56 a.m. ET, according to NASA’s Center for Near-Earth Object Studies. The center tracks Near-Earth Objects, or NEOs, that could collide with Earth.
NASA was tracking this particular asteroid for nearly the past 20 years. If you want to watch it live, you can watch the asteroid flyby live on The Virtual Telescope’s website.
ARE WE IN DANGER OF AN ASTEROID ATTACK? ASTEROID 2020 WILL SAFELY PASS EARTH IN APRIL? OR CAUSE ANY DAMAGE?
Here we all are listening about an asteroid. There are many questions that come in mind like what is an asteroid? will it safely pass? What is the history? And many more. So, here are the explanations for all such questions.
Overview
- Asteroids are extra from the development of our solar system about 4.6 billion years ago.
- There are thousands of asteroids develop each year.
- The large form of asteroids are known as planetoids.
- There are 3 types of asteroid.
- The effect on the impact on earth critically depends upon the size. Impact of Asteroid with earth resulting in the global environmental damage that will begin to mass destruction in which most life forms fall.
What is an asteroid?
Asteroids are minor planets that can neither be classified as a planet or comet. These are usually in close orbit nearby the Sun.
The large form of asteroids are known as planetoids.
There are many asteroids in our solar system. They probably live in the main asteroid zone between the orbits of Mars and Jupiter.
Formation of an asteroid?
Asteroids are extra from the development of our solar system about 4.6 billion years ago. There are thousands of asteroids develop each year. When our solar system had begun that were huge gases and dirt that dropped.
Some of the dust in the cloud became asteroids. The objects in the asteroid zone never had the chance to be consolidated into planets. They are leftovers from that time long ago when planets developed.
Asteroids types and composition
There are wide composition types of asteroids are as follow;
- The C type asteroid; also known as chondrite. They are most common consist of clay and silicate rocks. C types are dark in appearance with albedos typically in the 0.03 to 0.10 range. They occur mostly at the outer edge of the asteroid belt and less detectable contains 22% water.
They are the most ancient. Due to the fact that some have never even reached temperatures above 50°C
- The S type asteroid; also known as stony. They are made up of silicate and nickel-iron. S type exists in the inner asteroid belt.
- The M type asteroid; also known as metallic. They are made of nickel-iron and moderately bright (albedo 0.1–0.2). M types are also common types of the asteroid.
What would be the environmental effects if the earth collided with a large asteroid?
- The effect on the impact on earth critically depends upon the size. Impact of Asteroid with earth resulting in the global environmental damage that will begin to mass destruction in which most life forms fall.
- The impact of collision results in many forms like; the worst effects come from a global firestorm burned by back declining influence debris, and from a global pall of darkness that lasts for many months due to dust suspended in the second major layer of the earth’s atmosphere.
- The sky becomes filled with gazillions of fireballs
- It is as if the atmosphere itself has picked burning. The heat unleashed by this rain of radiant debris burns forests and towns, burning them to embers (coal).
- Sunlight would completely disappear for a month or so after a collision
- Temperatures down, and there is no daylight for photosynthesis.
- Plants and animals would die
- The heat of the impact also produces nitrogen oxides.
- The sulfurous material and nitrogen oxides make a corrosive acid rain that strips bare any surviving nature.
- The corrosive rainfall goes into the oceans and destroys aquatic organisms
- Nitrogen oxides and debris were thrown into the earth’s second major layer by the initial explosion that would damage the ozone layer within days.
- The influence and after fires also lose a huge amount of carbon dioxide into the environment
What were the asteroid hazards in the past?
- 65 million years ago, A 10 km asteroid strikes north of the Yucatan Peninsula, causes a global firestorm that destroys the dinosaurs.
- 3.3 million years ago, An impact in Argentina introduces numerous extinctions and a global cooling trend.
- 50,000 years ago, An meteorite a few meters across gouges the 1.2 kilometers in Arizona.
- In 1490, when an asteroids break overheads in China city name Chiling-yang causes the death of 10,000 people.
- In 1908, An asteroid of 50 meters exploded above Tunguska, Siberia. 200 square kilometers of trees were flattened, and the indigenous Evenki people who live in the area reported that their animals were thrown into the atmosphere by a shockwave.
- In 2013, The lights that appeared over Chelyabinsk, a city in southwest Russia, certainly were created by a superbolide. More than 1000 people were damaged by floating glass swelled out by the shockwave.
What can we learn from asteroids?
People and scientists can get a lot of information about the planets and the sun. Asteroids form at the same time as the other object in the solar system.
By learning the asteroids you will also know about the hazards it made in those mention cities.
Will an asteroid impact end humanity?
As we read above asteroids destroyed many countries and causes many deaths. When an influence event appears the tremendous active energy of the asteroid or meteorite a large body traveling at large speed is partly transported to the earth but largely turned it to heat and sound, creating pressure waves traveling radially outwards from its center, similar to the atom bomb.
It destroyed the dinasour. however, the meteorite created the opportunity for mammals to become dominant forms of life on earth.
The impact on bigger bodies are less common. The largest human history is the Tunguska event in Siberia in 1908.
How it safely pass through earth?
So, as we here the buzz about this asteroid that it will pas near from the earth. It won’t hit our planet or in fact not cause any damage to our earth.
The biggest asteroid coming closest on April 29, 2020. This space rock is apparently at least a distance wide (1.8 km) and possibly 2 1/2 times that big (4.1 km). The closest approach is April 29 around 5:56 a.m.
Let’s make it obvious that there is no chance of collision between earth and asteroid. Asteroid (52768) 1998 OR2 will pass at some 4 million miles (6 million km), or about 16 times the Earth-moon distance. It’s true that it is classified as the potentially hazardous asteroid.
