Wandering through the realms of the cosmos, pondering its huge vastness

Final Appearance of Venus in the Western Sky for 2010


In this image taken last October 3, the planet Venus was just 13.5 degrees above the western horizon at 6:18 PM (UTC+8), Apparent Magnitude: -4.44 A few days later, Venus was lost in the glare of the sun and set soon after it.

Shining high in the evening sky over the past few months, Venus is the brightest thing in the sky after the Sun and Moon. All this has changed rapidly. To those who have been watching Venus night after night, you have probably noticed that it is not as high in the sky as it was like a month before. Venus has gone lower and lower in the sky during the past few weeks and now it was no longer visible as it was too close to the Sun. On October 29, it will be in inferior conjunction, the time when Venus passes between the Sun and the Earth. During this period, Venus cannot be seen from Earth. It will disappear for a short period that averages 8 days until it becomes visible again in the morning sky, rising with the Sun (called heliacal rising).

After rising, Venus will reach its greatest brilliancy then its greatest western elongation, moving quickly (in retrograde motion) away from the Sun.
