Because opposition is when The Sun, the Earth and the planet are in a line. The planet appears opposite the Sun in the sky and the distance between Earth and planet is at a minimum.

How do you know if a plant is an inner or outer plant?

Inner planets orbit inside the orbit of the Earth, can only be seen in the morning or evening sky and are never seen as full disks form the Earth. Outer planets orbit further out than the orbit of Earth and can be seen from time to time as full disks in 'opposition' or overhead at midnight.


Comparing inner and outer planets movement?

The inner planets travel faster around the Sun because they are closer, while the outer planets take more time. The outer planets spin faster on their axis than the inner planets.


What is the difference of The rotational period of the inner and outer planets?

Rotational time of the planets is random (the length of the planet's day), but the outer planets do spin faster than the inner planets.


How do inner planets differ?

Inner planets differ from outer planets because they have rocky core (excepting Pluto), and the are much smaller than outer planets, which are bigger and take more time to orbit Sun than inner planets because of their location. Outer planets are farther from the Sun than inner planets.


How do the inner planets travel around the sun than the outer planets?

The inner planets (Mercury, Venus, Earth, Mars) have shorter orbits and faster speeds, completing their orbits in less time than the outer planets (Jupiter, Saturn, Uranus, Neptune). The inner planets are closer to the sun, so they experience stronger gravitational forces that cause them to orbit more rapidly, while the outer planets move more slowly due to their greater distance from the sun.

When planets move western and then return the normals motion?

It is called retograde motion which occurs round the time of opposition (outer planets only). Normally planets appear to move from west to east, in other words if they are in one position on a certain date, they will be east of that position 365 days later. The far-off planets Uranus and Neptune move only a little way along the ecliptic each year: 4.3 degrees for Uranus and 2.2 degrees for Neptune. However, when the planets are at opposition (exactly opposite the Sun, so they are south at midnight), they appear to be moving backwards (east to west) as the Earth overtakes them in their orbit. This is called retrograde motion, when they appear to move east to west from one night to the next. It happens for a few days around opposition for all the outer planets. The early orbital models of Ptolemy and Copernicus were able to predict retrograde motion correctly.


How do the orbits of the outer planets compare to the inner ones?

The outer planets take much more time and also travel longer to complete a whole orbit around the Sun, than the inner ones.


Why are the inner planets so much smaller then the gass giant outer planets?

The inner planets are smaller than the gas giant outer planets because they formed closer to the Sun where higher temperatures prevented gases from accumulating to form large planets. The outer planets had cooler temperatures, allowing them to accumulate large amounts of gas and become much larger in size.

What are all outer planets except pluto known to be?

The outer planets of the solar system are Jupiter, Saturn, Uranus, and Neptune. Pluto was also included as an outer planet from the time it was discovered in 1930 until being reclassified as a dwarf planet in 2006.


Why might the solar wind have a stonger effect on inner planets than on outer planets?

Inner planets like Earth have weaker magnetic fields compared to outer planets like Jupiter, which allows the solar wind to have a stronger impact. This is because the magnetic fields of outer planets can deflect and protect them from the solar wind, while inner planets are more vulnerable to its effects. Additionally, inner planets are closer to the sun where the solar wind originates, so they experience a more intense stream of particles.
