Venus is much brighter than any other planet viewed in Earthâs sky. Itâs the third-brightest object in the sky, after the sun and moon, and right now itâs at another time of greatest brilliancy on July 9-10, 2015. Look for Venus now in the west after sunset. Itâs near another very bright planet â but not as bright as Venus. The other planet is Jupiter.
Weâre able to see more distant objects if theyâre taller, like buildings or mountains, or when weâre higher up in the air. If you get to an altitude of 20 meters, the horizon stretches out to about 11 km. But we can see objects in space which are even more distant with the naked eye. The Moon is 385,000 km away and the Sun is a whopping 150 million km. Visible all the way down here on Earth, the most distant object in the solar system we can see, without a telescope, is Saturn at 1.5 billion km away. In the very darkest conditions, the human eye can see stars at magnitude 6.5 or greater. Which works about to about 9,000 individual stars. Sirius, the brightest star in the sky, is 8.6 light years. The most distant bright star, Deneb, is about 1500 light years away from Earth.
