Rearrange the following sentences (A), (B), (C), (D), and (E) to form a coherent paragraph, then answer the question.

(A) Furthermore, because this rogue planet does not emit any light of its own, locating it represents a major scientific breakthrough.
(B) Researchers estimate that there are about 100 million rogue planets in the Milky Way, but almost all of them are invisible.
(C) A recently published paper reveals that the nearest free-floating planet discovered is located only 1,560 light-years from Earth, a new study reports.
(D) Although this particular world is the closest rogue planet detected so far, it is highly unlikely to be the nearest one in existence.
(E) This wandering body, designated Rogue-9, is about 10 times the mass of Jupiter and orbits a dwarf star.

Which of the following will be the SECOND sentence after rearrangement?

To determine the correct second sentence in the paragraph, let us analyze the logical flow and connections between the given sentences:

(C) "A recently published paper reveals that the nearest free-floating planet discovered is located only 1,560 light-years from Earth, a new study reports."
This sentence serves as the ideal introductory sentence. It introduces the main topic: a newly discovered free-floating (rogue) planet and its distance from Earth.

(E) "This wandering body, designated Rogue-9, is about 10 times the mass of Jupiter and orbits a dwarf star."
This sentence logically follows sentence (C). The phrase "This wandering body" directly refers to the "nearest free-floating planet" introduced in sentence (C), giving specific details (its name, mass, and orbit) about it.

(A) "Furthermore, because this rogue planet does not emit any light of its own, locating it represents a major scientific breakthrough."
This sentence provides additional information about the planet introduced in sentences (C) and (E), starting with the transition word "Furthermore".

(D) "Although this particular world is the closest rogue planet detected so far, it is highly unlikely to be the nearest one in existence."
This sentence comments further on its proximity to Earth ("closest rogue planet detected so far").

(B) "Researchers estimate that there are about 100 million rogue planets in the Milky Way, but almost all of them are invisible."
This sentence expands on the general context of rogue planets in the Milky Way, serving as a concluding observation.

Therefore, the coherent sequence of sentences is C - E - A - D - B.

The sentence that comes SECOND in the arranged sequence is (E).

The correct option is E.
