What is a superior conjunction in astronomy?
A superior conjunction occurs when Earth and the other planet are on opposite sides of the Sun, but all three bodies are again nearly in a straight line. Superior planets, those having orbits larger than the Earth’s, can have only superior conjunctions with the Sun.
What is meant by conjunction in astronomy?
In astronomy, a conjunction occurs when any two astronomical objects (such as asteroids, moons, planets, and stars) appear to be close together in the sky, as observed from Earth.
What does inferior conjunction look like from Earth?
An inferior conjunction occurs when a Solar System body lies along a straight line between the Earth and the Sun. At this point, the elongation is zero degrees, and the body will have the same right ascension on the celestial sphere as the Sun. A planet at inferior conjunction, on a line between the Earth and the Sun.
Which planets can be at inferior conjunction?
Usually, though, when you hear the words inferior conjunction, astronomers are speaking of the planets Venus and Mercury, which orbit the sun inside Earth’s orbit. Astronomers sometimes refer to Venus and Mercury as inferior planets.
Can all planets come in one line?
The planets in our solar system never line up in one perfectly straight line like they show in the movies. In reality, the planets do not all orbit perfectly in the same plane. Instead, they swing about on different orbits in three dimensional space. For this reason, they will never be perfectly aligned.
Who was the first true astronomer?
In 1609, using this early version of the telescope, Galileo became the first person to record observations of the sky made with the help of a telescope. He soon made his first astronomical discovery.

The most commonly observed conjunctions involve the Moon, often as a crescent in the evening or morning sky, along with any of the bright planets – Venus, Mercury, Mars, Jupiter or Saturn.
What happens when all planets come in one line?
The planets in our solar system never line up in one perfectly straight line like they show in the movies. And this type of “alignment” almost never happens to all the planets, but instead happens to two or three planets at one time. The type of planetary alignment shown in this artistic rendering never happens.
What does inferior conjunction mean in astronomy and astrology?
inferior conjunction – (astronomy) the alignment of the Earth and a planet on the same side of the sun. astronomy, uranology – the branch of physics that studies celestial bodies and the universe as a whole.
When does an inferior planet transit the Sun?
~[ ⇑] Alignment of an inferior planet between the Earth and the Sun. If the alignment takes place at a favourable node, then the inferior planet may be seen to transit the Sun’s disk. conjunction occurs when two bodies have the same celestial longitude as viewed from the Earth. [>>>]
What does it mean when a planet is in conjunction with the Sun?
Inferior planets—those with orbits smaller than the Earth’s (namely, Venus and Mercury)—have two kinds of conjunctions with the Sun. An inferior conjunction occurs when the planet passes approximately between Earth and Sun; if it passes exactly between them, moving across the Sun’s face as seen from Earth, it is said to be in transit.
When does Venus meet the Sun in inferior conjunction?
Venus meets the sun in inferior conjunction on the 26th. While the ‘superior conjunction’ pertains to all planets in the solar system, an ‘ inferior conjunction ‘ only involves two planets – Mercury and Venus, the statement adds.
