The way to solve this is by putting each distance in terms of the same exponent, let that be 10¹⁵
The first becomes 176 × 10¹⁵
The second becomes 221.3 × 10¹⁵
The third becomes 3.1452 × 10¹⁵
The fourth remains 125.5 × 10¹⁵
It is now visible that the third and fourth stars are closest to the Earth and those should be the ones chosen for study.

What does the current OED reflect? FAST!!!
Kobotan [32]

The OED is not just a very large dictionary: it is also a historical dictionary, the most complete record of the English language ever assembled. It traces a word from its beginnings (which may be in Old or Middle English) to the present, showing the varied and changing ways in which it has been used and illustrating the changes with quotations which add to the historical and linguistic record. This can mean that the first sense shown is long obsolete, and that the modern use falls much later in the entry.
