In 2024, which newly discovered 'mini-moon' was expected to orbit Earth for about two months?

This question was previously asked in
SSC CHSL 2025 Tier 1 Question Paper (21-Nov-2025) (Shift 1)
The correct answer is

2024 PT5

The question asks for the small near-Earth asteroid that was expected to be temporarily captured by Earth's gravity as a 'mini-moon' in 2024.

The correct answer is 2024 PT5, a small asteroid discovered in 2024 that was expected to be loosely bound by Earth's gravity for about two months.

Belonging to the Arjuna asteroid belt, 2024 PT5 measured only around ten metres across and did not complete a full orbit but followed a horseshoe-like path near Earth.

Such temporarily captured objects are called mini-moons; they briefly accompany Earth before continuing on their own path around the Sun.

Aditya is the name of India's solar mission (Aditya-L1), not an asteroid, so it is unrelated to a mini-moon.

Cassini and Rosetta were famous space probes (to Saturn and to a comet respectively), not natural mini-moons of Earth.

Therefore the newly discovered mini-moon of 2024 was 2024 PT5.
