Specifically, at each apparition, Mercury reaches a separation from the Sun of between 18 and 28°. During its August–October 2020 apparition, it will reach a maximum separation of 25° to the Sun's east at greatest elongation.
Subsequently, one may also ask, how do you find the greatest elongation?
When an inferior planet is visible after sunset, it is near its greatest eastern elongation. When an inferior planet is visible before sunrise, it is near its greatest western elongation. The angle of the maximum elongation (east or west) for Mercury is between 18° and 28°, while that for Venus is between 45° and 47°.
Additionally, what is Planet elongation? The elongation is the angular separation between the Sun and a planet or other Solar System body as observed from the Earth. Elongations are measured in degrees eastward or westward of the Sun. The greatest eastward or westward elongation is the maximum angle between the Sun and a Solar System body.
Subsequently, one may also ask, what is the greatest elongation of Venus?
This month Venus reaches a point in its orbit known as greatest western elongation, a position where the angle between Earth, Venus and the Sun is 90˚, and the planet appears to be at its furthest west of the Sun.
Which planet has the most elongated orbit?
Pluto and Mercury are the planets in our solar system with the most eccentric orbits.

PtolemyWhich is the closest celestial body to our earth?
Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits.What is a synodic period?
Synodic period, the time required for a body within the solar system, such as a planet, the Moon, or an artificial Earth satellite, to return to the same or approximately the same position relative to the Sun as seen by an observer on the Earth.What is an inferior planet?
: either of the planets Mercury and Venus whose orbits lie within that of the earth — compare superior planet.When a superior planet is 180 degrees from the sun?
A superior planet is at opposition when it is on the opposite of the Earth to the Sun (elongation = 180 degrees).What planet is closest to the sun?
MercuryWhat is planetary configuration?
A planetary configuration just describes the location on the sky of a planet with respect to the Sun at any particular time. Also, the elongation of a planet is the angle between the planet and the Sun on the sky at any time.What is a superior conjunction?
A superior conjunction is when an object passes behind the sun from our point of view. Think of Venus or Mercury again. Half of their conjunctions with the sun – when they are brought together with the sun on our sky's dome – are inferior conjunctions, and half are superior conjunctions.What phase is Venus in now?
At this writing (late February 2020), Venus is in a waning gibbous phases. In other words, telescopic observers are seeing it as more than half lighted, but less than full. Here's the planet Venus seen through a telescope beginning in late February 2004.When would a new Venus be highest in the sky?
Because Venus is full when it is on the opposite side of the Sun from Earth, the Sun and Venus both appear to move through the sky together at that time. Venus therefore rises with the Sun, reaches its highest point at noon, and sets with the Sun. You just studied 5 terms!What angle is Venus?

What means orbit?
An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them. Planets, comets, asteroids and other objects in the solar system orbit the sun.Which is the largest and most massive of the planets in our solar system?
Largest Planet: JupiterThe largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter's mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth's diameter.

Which planet was named after the Roman god of war?
MarsAt what configuration would it be best to observe?
The best configuration to observe a planet is when it is at the greatest angular distance from the Sun. This is Greatest Elongation for the inferior planets and Opposition for the superior planets.Which planets are the inferior planets?
The inferior planets are those which orbit closer to the Sun than the Earth, namely Mercury and Venus. They are seen to undergo phases ranging from crescent to full, and also exhibit retrograde motion.What is Moon elongation?
The elongation of the Moon is the apparent angular distance of the center of the Moon from the center of the Sun as seen by a particular observer. - Jim Mosher.Which period of a superior planet is longer?
Mercury has the shortest synodic period, namely 116 days. The synodic periods of all superior planets are greater than one sidereal year. The synodic periods of inferior planets may be less than (Mercury) or greater that (Venus) one sidereal year.Which planet has 6 month long seasons?
Martian seasons are peculiar by Earth standards, but they probably pale in comparison to seasons on Uranus. Like Earth, the orbit of Uranus is nearly circular so it keeps the same distance from the Sun throughout its long year. But, Uranus's spin axis is tilted by a whopping 82 degrees!Which is not considered a terrestrial planet?
Non-terrestrial planetsIn our solar system, Jupiter, Saturn, Uranus and Neptune are gas giants, also known as Jovian planets.
