Source sentences:
text: At aphelion Mercury is over 20% further from the Sun than normal, and as a result moves about 17% slower than normal in its orbit around the Sun; and being 20% further away than usual, even if it were moving at the same speed as usual
text: At perihelion, on the other hand, Mercury is over 20% closer to the Sun than normal, and as a result moves about 25% faster than normal in its orbit; and being 20% closer than usual, even if it were moving at the same speed as usual it would look like it was moving faster (the exact opposite of the situation described for aphelion), at least in terms of its angular velocity around the Sun.
