Venus rises heliacaly when reaching arcus visionis between 5.3 and 6.0 degrees.
(Arcus visionis is the altitude of the Sun below horizon when Venus is exactly on the horizon).
Because Venus is bright and its brightness is stable, the heliacal rise of Venus can be computed easily. Something that cannot be said for the other planets and stars. The last systematic (and published) observations of heliacal risings were made 2000 years ago in Mesopotamia!
There are several theoretical algorithms for computing the heliacal phenomena, but none of them is reliable because of the lack of observations.
This is soon to be changed.

When will Venus align with the Leo constellation?
Venus can align with the Leo constellation at different times depending on their respective positions in the sky. Generally, Venus and Leo are most likely to align during the evening hours when Venus is visible in the western sky and Leo is rising in the east. The exact timing can vary throughout the year due to the movement of both Venus and the constellations in the sky.

Does Venus' have any active volcanos?
Venus currently has some active volcanoes with lava flows, but the vast majority are inactive, dormant, or extinct. Venus does not have plate movement, which causes volcanoes on Earth. The driving force is likely heat rising from hot spots in the lower crust or upper mantle, as is seen in some volcanic seamounts on Earth.
Does Venus have no sunrise?
Venus has perpetual very thick cloud layers, so on the surface there would be no visible sunrise. If the clouds were somehow removed, then there would be a sunrise, but because Venus rotates so slowly (and in the wrong direction) it would be a bit different than an Earthly sunrise.
