What is a Etiam?
What is a Etiam?
A very large asteroid (called Etiam) that is capable of destroying most life on Earth is headed our way. Once your group makes a decision on what your solution to save earth is, your group will create a video news segment that describes how you plan to prevent this impending collision.
What would happen if a giant asteroid hit the earth?
With an asteroid hitting the Earth; dust and smoke rising in the atmosphere prevents sunlight from reaching our world and causes the total temperature to drop. This event can lead to the death of many living things. If an asteroid the size of an apartment hits Earth, this blow could possibly destroy a small city.
What will happen in 2135?
21, 2135, be warned that you might end up having to blow them off — no pun intended. That’s the day that an asteroid measuring 200 metres across could slam into the Earth, unleashing an amount of energy 80,000 times more powerful than the nuclear bomb that devastated Hiroshima in August 1945, according to NASA.
Will another asteroid hit Earth?
Currently none are predicted (the single highest probability impact currently listed is ~7 m asteroid 2010 RF12, which is due to pass earth in September 2095 with only a 5% predicted chance of impacting). Currently prediction is mainly based on cataloging asteroids years before they are due to impact.
Has any comet hit Earth?
The Chelyabinsk meteor was estimated to have caused over $30 million in damage. It is the largest recorded object to have encountered the Earth since the 1908 Tunguska event.
Is there a comet coming?
Around December 14-16, 2021, Comet C/2021 A1 (Leonard) will become visible just after sunset, very low in the southwest horizon, as seen from U.S. See additional charts below: Location of Comet C/2021 A1 (Leonard) on December 15, 2021, about 30 minutes after sunset.
Which comet will hit Earth?
On average, an asteroid the size of Apophis (370 metres) can be expected to impact Earth once in about 80,000 years….99942 Apophis.

Is a comet dangerous?
A potentially hazardous object (PHO) is a near-Earth object – either an asteroid or a comet – with an orbit that can make close approaches to the Earth and large enough to cause significant regional damage in the event of impact. Most of these objects are potentially hazardous asteroids (PHAs), and a few are comets.
Will a comet collide with Earth?
NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small. In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.
How powerful is a comet?
Because of the comet’s high orbital eccentricity, 0.9951, and inclination, 89.43°, the impact velocity would be 52.9 km (32.9 miles) per second. The resulting impact energy is equivalent to 4.4 billion megatons of TNT. Thus, the largest and most-devastating impacts on Earth are likely to be comets.
Are comets bigger than Earth?
Comets are frozen leftovers from the formation of the solar system composed of dust, rock and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
Is it a comet is it an asteroid?
Because they formed in the deep freeze of the outer solar system, comets are icier than asteroids. They’re composed of rock and ice, earning them the nickname dirty snowballs. It’s when comets sweep in close to the sun that they produce their characteristic gas and dust tails. Comets are named for their discoverers.
