Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 35-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

About this test

Universe and Solar System GK Questions Level 3: Hard Practice Set

This Level 3 GK practice set tests whether you can separate closely worded facts about the universe and solar system, from the Big Bang and galaxies to planets, the Moon and Pluto. It relies on statement-based, matching and chronology questions. Aptitude360 explains the answer to every question.

Topics covered in this Universe and Solar System set

  • Origin of the universe: the Big Bang and Edwin Hubble's evidence that the universe is expanding
  • Galaxies and the Milky Way, known in India as Akash Ganga
  • Stars and constellations, the Saptarishi in Ursa Major and how it helps locate the Pole Star
  • Order of planets from the Sun, the planet mnemonic and the rocky inner planets
  • The Earth's geoid shape, its size rank and how it compares with Venus
  • The Moon, asteroids between Mars and Jupiter, meteoroids, and Pluto's reclassification as a dwarf planet

Key concepts to revise for solar system GK

  • A light year is a unit of distance, not of time
  • The difference between a star, a planet, a satellite and a constellation
  • Chronology of events, from the Big Bang and the formation of the planets to the first Moon landing
  • Approximate distances and timings such as Sun to Earth, Earth to Moon and sunlight's travel time
  • Who is linked with what: Hubble, Neil Armstrong and the International Astronomical Union

How to prepare for hard solar system questions

  • Write the planets in order on one line and place the asteroid belt between Mars and Jupiter
  • Keep a short table of key distances and ages so wrong pairings in matching options are easy to spot
  • Read each statement separately, since swapping one word such as planet for star changes the answer

Who should take this Level 3 quiz

General Awareness aspirants who have already covered solar system basics and now want harder statement, matching and sequence practice.

FAQs about Universe and Solar System – GK Quiz with Answers – Level 3

What is a light year?
A light year is a unit of distance. It is the distance light travels in one year and is used to measure distances between stars and galaxies.
Why is Pluto not a planet anymore?
In 2006 the International Astronomical Union classified Pluto as a dwarf planet because it does not meet all the conditions the IAU set for a full planet.
Which planets are called terrestrial planets?
Mercury, Venus, Earth and Mars are the terrestrial planets. They are the four inner planets and are made of rock.
Why is Venus called Earth's twin?
Venus is called Earth's twin because it is similar to the Earth in size and shape. Its conditions, however, do not support life.
