Astronomy Exam #1
What is a celeb? - ANSA superstar is a massive luminous ball of gasoline that generates
warmness and light through nuclear fusion.
What is a planet? - ANSA planet is a moderately huge object that orbits a star. It shines
through reflected mild.
Planets can be icy or rocky
What is a moon? - ANSA moon (or satellite) is an object that orbits the planet.
What is an asteroid? - ANSAn asteroid is a small and ROCKY object that orbits a star.
What is a comet? - ANSA comet is small and ICY item that orbits a celebrity.
What is the SOLAR SYSTEM? - ANSThe sun system is a star and all the cloth that orbits it;
such as it planets, moons and asteroids.
Our Solar System is the Sun, Earth, Mars...
What is a nebula? - ANSA nebula is an in stellar cloud of gas and or dust and it's miles
indicative of big name start or superstar dying.
What is a galaxy? - ANSA galaxy is a extraordinary is a awesome island of stars in area, all
held collectively by means of gravity orbiting the not unusual center.
An instance: The Milky Way
What is a Local Supercluster? - ANSA nearby supercluster is businesses of galaxies which
might be generally clustered
What is the definition of a Universe? - ANSThe universe is the sum overall of all be counted
and electricity this is the whole thing within and between all galaxies.
What are the 2 elements that the whole lot comes from because the Big Bang? - ANSThe
elements are Hydrogen and Helium.
H + He
How big is a Light Year? - ANSa light 12 months is 300 thousand kilometers in keeping with
second or 300 million minutes in step with second.
3x10⁸ m/s
About 10 trillion kilometers
, What is the equation for one mild year and what does a light year degree? - ANSA mild 12
months equals the velocity of mild times three hundred and sixty five days.
A mild 12 months measures distance.
Powers of 10 - ANS10⁶ = one million
10⁰ = 1
10⁻¹ = 0.1
Powers of 10: Rule of Multiplication - ANS10^A x 10^B = 10^(A+B)
Powers of 10: Rule of Division - ANS10^A / 10^B = 10^(A-B)
The LARGE Scale Nomenclature - ANSKilo = 1,000 = 10³
Mega = one million =10⁶
Giga = a million,000 = 10⁹
Tera = 1,000,000,000,000 = 10¹²
The SMALL Scale Nomenclature - ANSMilli = zero.001 = 10⁻³
Micro = zero.000001 = 10⁻⁶
Nano = 0.000000001 = 10⁻⁹
Pano = zero.000000000001 = 10⁻¹²
How Big Is The Universe? - ANSThe universe is set four hundred billion stars inside the
Milky Way.
The Milky Way is one of about one hundred billion galaxies
There are as many stars as the amount of grains of sand.
10¹¹ stars times 10¹¹ galaxies equals approximately 10²² stars in the universe.
What is the Cosmic Calendar? - ANSThe cosmic calendar is a scale on which we compress
the history of the universe into 1 12 months.
For instance: In a cosmic year, human existence in about a 2nd.
In what methods do humans appoint clinical thinking? - ANSScientific thinking is based on
normal thoughts of remark and trial-and-error experiments.
What are the dangers of commonplace experience? - ANSCommon feel often works
properly for humans and generally breaks down at the frontiers of technology.
For example, by means of pronouncing the earth is not flat being compared to earth orbits
the solar wishes technological know-how to prove it.
What are facts? - ANSFacts are from time to time called empirical evidence and derived
from experiments and they have to be repeatable.
What is a celeb? - ANSA superstar is a massive luminous ball of gasoline that generates
warmness and light through nuclear fusion.
