Because many very clever people studied it for many hundreds of years, and finally they came up with a theory that explains how the planets move.
It was not simple and it needed the best minds available to the human race to study it for that long. It was a tantalising problem but in the end not too difficult to force them to give up.
Claudius Ptolemy thought he had it all sorted in AD 100 with his model of the planets with many circles and epicycles. It predicted the positions of planets in the sky pretty well, but many many years later, around 1600, Galileo discovered the full range of Venus's phases, which Ptolemy's model failed to explain.
Around the same time, Joannes Kepler produced a new model which had the planets following elliptical orbits round the Sun which was at the centre. After Newton's later theoretical discoveries everyone was forced to accept that Kepler's model must be correct.
At midnight lately, the planet Saturn has been visible in the southern sky. Saturn reaches opposition in July, making it more prominent and easy to spot in the night sky.
Jupiter is most visible in the night sky during the months of June and July. This is when the planet is closest to Earth and appears brightest.
Venus is the brightest planet in the sky. It is often referred to as the "evening star" when visible in the western sky after sunset or the "morning star" when visible in the eastern sky before sunrise.
Mars is easily visible high in the evening sky this season. ============================================ Also ... Saturn is rising in the southeast, visible by 9 PM, almost due south by 12 Midnight. Mercury, Venus, and Jupiter are there, but all appear too close to the sun to be easily visible, for at least several more weeks.
Venus is currently visible as a very bright evening star in the night sky after sunset. It is the third brightest object in the sky after the sun and the moon. Venus is often referred to as the "evening star" when it is seen in the west after sunset.
why do scientists aew able to predict where in the night sky a planet will be visible
Scientists can predict the position of planets in the night sky using mathematical models based on our understanding of planetary motion. By taking into account the planet's orbit, speed, and gravitational interactions with other celestial bodies, scientists can accurately calculate its position at any given time. This information allows them to forecast when and where the planet will be visible from Earth.
Venus is usually the planet that is most thought to be a UFO, but all planets visible without a telescope or binoculars can be mistaken for UFOs.
Yes, the planet Mars is visible to the naked eye.

Venus is the most visible planet from Earth. It is often referred to as the "evening star" or "morning star" because it can be seen shortly after sunset or before sunrise. Its brightness is due to the reflection of sunlight off its thick cloud cover.
Definitely, although it's often difficult to aim a serious telescope down, belowthe horizontal. Fortunately, our planet is also easily visible without a telescope,in daylight as well as at night.
Yes, easily. It can be seen with the naked eye easily too. However, Venus is only visible either just before dawn or just after sunset; it is never visible in the middle of the night.
the naked eye determines if it is visible.
Venus' atmosphere makes the planet bright with sun rays reflecting against it.
Venus is the brightest planet in the night sky. It is often referred to as the "evening star" when it is visible after sunset or as the "morning star" when it is visible before sunrise. Venus's brightness is due to its thick cloud cover that reflects sunlight very effectively.
