Jupiter does not show obvious phases, unlike the Moon, Venus and Mercury. Those phases are caused by the changing angles as the body and the Earth proceed through their orbits, so that the angle at which we see their day sides changes. Jupiter is too far away for the difference in angle of observation to make an appreciable difference.
The planets that can cross the face of the Sun in transit are Mercury and Venus. They have specific orbital patterns that align with the Sun to create these rare events, known as Mercury transits and Venus transits. After 122 years, both Mercury and Venus would have completed multiple transit events.
You can detect planets around are star only if they are of sufficient mass, They will cause the star to wobble (due to its gravity) as it rotates this can be seen and the position of the planet inferred.
1) Although planets can be composed primarily of rock or gas, only stars are objects made of gas that are massive enough to support a nuclear fusion reaction. 2) Although planets and stars can orbit stars (as in binary systems), stars never orbit planets.
Jovian planets are generally considered more evolved than terrestrial planets. They have larger sizes and more complex structures due to their higher gravity and gas composition. Terrestrial planets are usually simpler in structure and composition, as they are predominantly made of rock and metal.
Stars are massive celestial objects primarily composed of hydrogen and helium that generate energy through nuclear fusion. Planets, on the other hand, are smaller celestial bodies that orbit around stars and do not produce their own light. Planets can be rocky, gaseous, or icy, and they do not undergo nuclear fusion like stars do.
the two planets that can be viewed from earth are Mercury and venus.

Planetary transits are the motion of the planet through the zodiac in respect to your birth chart's Rashi (Moon-sign). The planets influence your life in specific ways as they travel through the signs.

There are several types of land survey transits including optical transits, digital transits, and laser transits. Optical transits use optics and a spirit level for accuracy, digital transits include electronic measurement capabilities, and laser transits use a laser beam for precise measurements. Each type has its own advantages and is used for different surveying applications.
In a very few recent cases we have directly observed the planets. Most exoplanets (planets orbiting other stars) are detected through periodic wobbles in the light of the star as the planet makes its way around. That may change this month with the launch of the Kepler satellite later today. The third way to detect planets is by their transits. If the distant planet crosses in front of the star and us, the star light dims in a characteristic manner. Kepler will observe thousands and thousands of stars for transits.
Venus transits are rare because of the alignment of the orbits of Venus and Earth. The two planets must be in precise positions for a transit to occur, which only happens every 243 years in pairs separated by about 8 years. This rarity makes Venus transits significant events for astronomers.
The official definition of the word transits is "the carrying of people, goods, or materials from one place to another."
The inner planets, Mercury and Venus, are too small and too far away to block more than a tiny part of the Sun (less than 1%). So even when they are aligned with the Sun (which is veryrarely), they are practically invisible to the naked eye.Transit of Venus 2012Both Mercury and Venus make "transits" across the Sun, as seen from the Earth, at very long intervals. Mercury's transits are nearly invisible because of the distance from Earth, but happen about 13 or 14 times every 100 years. The next will occur in 2016. Venus is closer to the Earth and makes a shadow about 1/30th of the Sun's diameter. But because of the inclinations of the planets' orbits, transits of Venus only occur every 105 or 121 years, as pairs of transits 8 years apart. The transit following 2004 will be on June 6, 2012 and it will not occur again until the years 2117 and 2125. In 2012, the best visibility will be in the mid-Pacific and in Australia.As viewed from an outer planet, eclipses by inner planets are very rare. The transit of Jupiter as seen from Saturn would be the most noticeable, about the same as Venus from Earth. But the transits can be more than 2400 Earth years apart.

Planets form, and they undergo changes as they age. This process of change might be termed 'geological evolution', but this should not be confused with biological evolution, which is an entirely different kind of process.
