There is a quasi-mythical attribution of the term to Edmund Burke, which Jeffrey Archer summed up in his novel, The Fourth Estate : In May 1789, Louis XVI summoned to Versailles a full meeting of the Estate General. The First Estate consisted of three hundred clergy. The Second Estate, three hundred nobles. The Third Estate, six hundred commoners. Some years later, after the French Revolution, Edmund Burke, looking up at the Press Gallery of the House of Commons, said, 'Yonder sits the Fourth Estate, and they are more important than them all.'.
When Venus is on the far side of the Sun from Earth, it can be as far as 261 million kilometers away. That varies widely, depending on which part of the orbit the Earth and Venus is. At its closest - during an inferior conjunction - Venus is at a distance of about 41 million kilometers.
Please note that the distance from Earth to Moon is quite insignificant compared with the distances to the Sun, or to other planets.<br />So, how far is Venus from Earth?<br />Unfortunately there's no fixed answer because the distance is always changing, as the planets move in their orbits.
