Near Earth Objects: A Quiz To Test Your Knowledge!

1. Which of the following is a result of asteroids hitting water bodies?

Tsunamis

Flood

Landslide

Vulcanoes

Asteroids hitting water bodies can cause tsunamis. When an asteroid collides with a body of water, it creates a large displacement of water, resulting in the formation of massive waves. These waves can travel across the ocean at high speeds and cause widespread destruction when they reach the coastlines, resulting in tsunamis.

2. Which of the following qualifies a solar system body as a NEO?

If its closest approach to the sun is less than 1.3 astronomical units

If its closest approach to the sun is less than 1.7 astronomical units

If its closest approach to the sun is less than 1.5 astronomical units

If its closest approach to the sun is less than 1.4 astronomical units

A solar system body qualifies as a NEO if its closest approach to the sun is less than 1.3 astronomical units. This means that the body's orbit brings it closer to the sun than the distance between the sun and Earth at its closest point. This criterion is used to categorize objects that have the potential to come close to Earth's orbit and potentially pose a risk of collision.

3. When is a NEO considered a potentially hazardous object?

If its orbit crosses the Earths and it's larger than 140 meters

If its orbit crosses the Earths and it's larger than 120 meters

If its orbit crosses the Earths and it's larger than 100 meters

If its orbit crosses the Earths and it's larger than 130 meters

A Near-Earth Object (NEO) is considered a potentially hazardous object if its orbit crosses the Earth's orbit and it is larger than 140 meters. This means that the NEO has the potential to come close to Earth and pose a threat of impact due to its size and proximity.

7. As of March 15, 2017, how many NEAs were known to have at least one moon?

59

37

66

72

As of March 15, 2017, there were 66 near-Earth asteroids (NEAs) known to have at least one moon.

Explanation

As of March 15, 2017, there were 66 near-Earth asteroids (NEAs) known to have at least one moon.

8. There are how many known NEOs?

19,220

19,000

19,229

18,589

There are 19,229 known Near-Earth Objects (NEOs). This refers to asteroids and comets that come within 1.3 astronomical units of the Earth's orbit. These objects are closely monitored by scientists to track their trajectories and assess any potential risks of collision with our planet. The number constantly changes as new NEOs are discovered and existing ones are tracked more accurately.
