The planets move through all the signs of the zodiac. So, at times Venus is in Aquarius.
Currently, May 1, 2016, in the tropical zodiac Venus has just moved into Taurus. At this moment, no it is not near either constellation.
Mars has a fast moving and somewhat erratic orbit around the Sun. It is not consistently in any one sign at a given time of each year . It takes about a year and a half to make its revolution around the Sun ( meaning to get back to the same sign) so it could be in the sign Aquarius in any season of a year. Venus and Mercury for example are never too far away from the Sun's place in the Zodiac , so you could reasonably ask that question about those two planets. For example Venus in Aquarius would be in Aquarius anywhere between early winter and early spring; which is near the time that the Sun is also in Aquarius.
A male Capricorn should marry a Capricorn, Taurus, Virgo, Cancer, Scorpio, or Pisces (all feminine signs), but if a Sagittarius or Aquarius has Mercury, Venus, or Mars in Capricorn, or if the Capricorn has those planets in Sagittarius or Aquarius, then marrying a Sagittarius or Aquarius would work too.
The #1 important was Aquarius because Aquarius is Greek.
