Venus' Synodic Year: Why Does It Take Longer Than Earth's?

AI Thread Summary
Venus takes approximately 225 Earth days to complete one orbit around the Sun, while its slow axial rotation takes about 243 Earth days. This confusion often arises from mixing up the concepts of rotation (spinning on its axis) and revolution (orbiting the Sun). A synodic year for Venus, which is the time it takes to appear in the same position relative to Earth, is about 1.6 years. This longer synodic year occurs because Venus must travel additional distance to catch up with Earth after completing its orbit. Understanding these distinctions clarifies why Venus has a longer synodic year than Earth.

Why do venus take more number of days for one complete rotation around sun than Earth when the gravitational pull towards venus is higher than Earth ?

It doesn't. Google is your friend.

Maybe you're thinking about the rotation of Venus as opposed to the orbit of Venus? Venus spins on its axis very slowly, so it only makes a full axial rotation ever 243 Earth-days, but in this time period it has already made a full orbiting loop around the Sun and is about 8% of the way into the next loop.
 
Probably a definition issue:
Rotation: spinning about its axis
Revolution: moving around the sun
 
Perhaps you're thinking of a synodic year. Venus takes about 1.6 years to complete a cycle as seen from Earth. After it completes one orbit, it still has to travel an extra distance to catch up to Earth, which has also moved. So from one apparition as an evening star to the next it takes 1.6 years.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
