Q:

A Larger Venus in Our Solar System

Related to If Mars Were a Superearth
In terms of diameter and mass, Venus is one step close to identical to Earth.
But in this scenario, Venus is actually the size of the one exoplanet that astronomers had been calling a "Super-Venus"--Gliese 832c.

The mass of the planet varies between 5.5 and 10.4 times higher than Earth's.  Unlike the previous planet enlargement question, which put Kepler-10b 225 million miles away from Earth, this super-rock is considerably closer to Earth--almost 27 million miles away.  So if the planet Venus were enlarged to the size of Gliese 832c, would it affect Earth's orbit in any way?  What would the nightscape look like with a larger Venus?

A:

It would perturb the orbit a bit but not enough to change much. i.e. the change would be calculatable but would not change the weather or seasons enough to matter.
Phosphorous and Heosphoros$^1$ would be brighter and would be visible later and earlier respectively. Making them even more important in mythology and popular culture. If it were big enough to be seen as a disk heliocentrism would have had better traction earlier. Unfortunately, it would just be marginally brighter. 
$^1$ the morning and evening stars i.e. Venus in the morning and evening. the stars you wish on.
