A telescope allows us to see very faint objects mostly due to the large size of the opening that light passes through, known as the aperture. Like the pupil in the human eye, the larger the diameter of a telescope’s aperture, the fainter the objects we can detect with it. An amateur astronomer claims that she likely could see most, but not all, of the stars in the table while using a telescope with a 160-millimeter (mm) aperture.
Which choice best describes data from the table that support the amateur astronomer’s claim?
A
Only Sk-69 249 A can be seen from Earth using a telescope with a 60 mm aperture.
B
Only Melnick 34 requires a telescope with a minimum aperture greater than 160 mm.
C
Only VFTS 182 is further than 163,000 light-years from Earth.
D
All four stars can be seen from Earth using a telescope with a 160 mm aperture.
