Mercury has a double sunrise.
You can only see Mercury at sunrise and sunset.
Mercury has a double sunrise because when the sun rises a bit, an orbital effect makes it sink down and rise again.
It depends on the relative positions of Earth, Mercury, and the sun at the time. Sometimes Mercury is hidden behind or in the glare of the sun. At other times Mercury may be seen shortly before sunrise or shortly after sunset.
at nightnime Depending on Mercury's position, the longest you can see it, is about 1 hour after sunset or 1 hour before sunrise, and when Mercury is at a right angle from the sun as viewed from Earth. This is when Mercury appears to be farthest from the sun. As Mercury orbits the sun, it appears to be closer to the sun, and will be visible for a shorter amount of time. You will need to have an unobstructed view of the horizon.
The answer is NOT Venus. It is MERCURY. Venus takes longer to spin once than does Mercury. However Venus spins in the opposite direction to Mercury. The result is that Mercury has the longest "sunrise to sunrise" times.

Either just before sunrise or just after sunset (at any given time it's either one or the other, not both).

The sunrise time on January 21, 2009, would depend on the specific location, as sunrise times vary by location. You can check the exact sunrise time for that date and location by using an online sunrise/sunset calculator or checking a local almanac.
Venus has the longest sidereal day (period of rotation or spin). This "day" is 243.0185 Earth days long and Venus rotates in the opposite direction of Earth. This day on Venus is actually longer than its "year". It takes more time for the planet to turn one time on its axis than it takes to go around the Sun. A "year" on Venus takes only 224.7 Earth days.However, the longest solar day occurs on Mercury, which completes its slow spin about once every 59 Earth days but also circles the Sun in just 88 Earth days. This tidally-locked combination leads to a solar day (roughly sunrise to sunrise) of 176 Earth days, twice as long as the "year".On Venus, because it rotates clockwise but orbits counter-clockwise, the effect is to make a solar day ("daytime" is brighter, but there's no sunrise through the clouds) about 116.75 Earth days.Minor comment: The actual question may be asking something different, but that's not clear.
