The imaginary line is called the Tropic of Cancer because when it was named, the Sun was in the direction of the constellation Cancer at the June solstice. However, this is no longer true due to the precession of the equinoxes. According to International Astronomical Union boundaries, the Sun now is in Taurus at the June solstice. According to sidereal Astrology, which divides the zodiac into 12 equal parts, the Sun is in Gemini at that time. The word "tropic" itself comes from the Greek τροπή (tropi), meaning turn, referring to the fact that the Sun appears to "turn back" at the solstices.
