please no plagiarism
you will need to reference the Asteroid Day web page at: https://asteroidday.org/ . Scroll down to the “Asteroid Education” links - Using the “Asteroid Basics” link find answers to the following 4 questions:
1/ Write down the definition that applies to the orbit of an Apollo near-Earth asteroid
. 2/ Write down the definition that applies to the orbit of an Aten near-Earth asteroid.
3/ Write down the definition that applies to the orbit of an Amor near-Earth asteroid.
4/ When, where and who discovered the first near-Earth asteroid, and what is its name?
5/ Use the internet (e.g., Wikipedia) to find the semi-major axis a, perihelion q, and aphelion Q distances of asteroid 4179 Toutatis (shown left), write them down and explain what sort of NEA object it is (Apollo, Amor or Aten).
a (AU) =
q (AU) =
Q (AU) =
6/ From the “Asteroid Deflection” link - https://resources.asteroidday.org/ed/asteroid-deflection/ – describe in more than 200 words but less than 300 (do not cut and paste) one method by which an asteroid might be deflected to avoid an immanent Earth impact.
Explanation / Answer
1. Apollos Earth-crossing NEAs with semi-major axes larger than Earth’s (named after asteroid 1862 Apollo).
a>1.0 AU, q<1.017 AU
2. Atens Earth-crossing NEAs with semi-major axes smaller than Earth’s (named after asteroid 2062 Aten).
a<1.0 AU, Q>0.983 AU
3. Amors Earth-approaching NEAs with orbits exterior to Earth’s but interior to Mars’ (named after asteroid 1221 Amor).
a>1.0 AU, 1.017<q<1.3 AU
4. The first NEA was discovered by Gustav Witt from the Urania Sternwarte Berlin and independently found by Auguste Charlois from the Observatoire de Nice, on 13 August 1898. It's name is (433) Eros.
5. FOr asteroid 4179 Toutatis, we have
a (AU) = 2.5321
q (AU) = 0.9399
Q (AU) = 4.1242
From definition 1, it is an Apollo.
