There are five planets visible to the naked eye; Mercury, Venus, Mars, Jupiter and Saturn. However, Mercury and Venus are interior planets (closer to the Sun that we are) and are never seen in the "full" phase. Mars, Jupiter and Saturn are never seen in the "new" phase, because they never pass between Earth and the Sun. Note: This is requirement 5.1 for the Astronomy merit badge.
Venus goes through four main phases similar to the Moon: new, crescent, quarter, and full. These phases result from the varying positions of Venus in relation to the Earth and the Sun, affecting how much of the illuminated side of Venus is visible from Earth.
During the inferior conjunction phase of Venus, it is possible to see the planet partially eclipsed by the Sun. This occurs when Venus passes between the Earth and the Sun, appearing as a small silhouette against the solar disk. Viewing this event requires proper solar viewing equipment to avoid eye damage.
venus completes an orbit every 224.65 days.
No, Venus rotates on its axis in the opposite direction to most other planets, so it experiences retrograde rotation. As a result, different sides of Venus are visible from Earth at different times.
Venus would never be visible as a crescent phase because it is an inner planet whose orbit is between Earth and the Sun. This means that Venus can never appear to us in crescent phase, as it would always show either a full or nearly full phase when viewed from Earth.
When Venus is in its full phase, Earth would appear in its new phase as seen by a hypothetical Venetian. This is because the position of Earth in relation to the Sun would cause it to appear fully illuminated from Venus, similar to how Venus appears fully illuminated from Earth during its full phase.
One side of the moon (the Earth facing side) becomes fully visible at Full Moon.

When the moon is fully visible to observers on Earth, it is said to be at its full moon phase. This occurs when the sun, Earth, and moon are aligned in a straight line, with the Earth in between the sun and moon. The full moon appears as a complete circle and is the brightest phase of the moon.
The planet Venus is _NEVER_ seen in the full phase, because it never gets anywhere near the Earth. Venus is in a closer orbit to the Sun than the Earth is, so when Venus is closest to the Earth, it's pretty close to being between the Earth and the Sun. In fact, Venus passes directly between the Earth and the Sun twice per century, most recently in 2004. We call this a "transit of Venus".So we only see Venus in its crescent phases.Think about it . . . In order to see the complete illuminated side of Venus,we'd have to be looking at it through the sun.
Venus goes through four main phases similar to the Moon: new, crescent, quarter, and full. These phases result from the varying positions of Venus in relation to the Earth and the Sun, affecting how much of the illuminated side of Venus is visible from Earth.
After the full moon phase, the moon's illumination begins to decrease as it moves towards the new moon phase. This is known as the waning phase, where less and less of the moon's illuminated surface is visible from Earth.
The phase of the full moon is when the moon appears fully illuminated, while the phase of the new moon is when the moon is completely dark or not visible from Earth.
How much of it is visible from earth, ie half moon, full moon etc. These are the phases
