UPSC Prelims 2027 CGS Test-9
1. Consider the following pairs of space missions and their descriptions:
- PLATO: Aims to identify Earth-sized planets orbiting Sun-like stars
- Ariel: Conducts chemical surveys of transiting exoplanet atmospheres
- Akatsuki: Japanese telescope researching dark matter and dark energy
Which of the above pairs are correctly matched?
[A] Only one
[B] Only two
[C] All three
[D] None
Show Answer
Correct Answer: B [Only two]
Notes:
PLATO is designed to study rocky, Earth-like planets orbiting Sun-like stars. Ariel will examine the atmospheres of a large sample of exoplanets, including through chemical analysis. Akatsuki is Japan’s Venus Climate Orbiter; it observes Venus’s atmosphere and investigates its circulation, clouds and related phenomena. It is not a dark-matter or dark-energy research telescope. Thus, the PLATO and Ariel pairs are correctly matched, while the Akatsuki pair is not.
2. Consider the following celestial bodies:
- GJ 3378 b
- 55 Cancri e
- L 98-59 d
- TRAPPIST-1 e
Which of the exoplanets listed above are classified as “Super-Earths”?
[A] 1 and 2 only
[B] 1, 2 and 3 only
[C] 2, 3 and 4 only
[D] 1, 2, 3 and 4
Show Answer
Correct Answer: B [1, 2 and 3 only]
Notes:
GJ 3378 b, 55 Cancri e and L 98-59 d are classified as Super-Earth exoplanets. NASA identifies 55 Cancri e and L 98-59 d as Super-Earths, and GJ 3378 b is described as a Super-Earth in research reporting its measured mass. TRAPPIST-1 e is an Earth-sized terrestrial planet. Therefore, the correct set is 1, 2 and 3 only.
