What is the best time to observe Venus?

The best time for planetary observation is when it is the closest to us on Earth. Venus is the second and Earth is the third closest planet to the Sun. That means Venus precedes the Sun in its path, so it will not be visible in the middle of the night. You have to look for it at the beginning or the end of the night.

The greatest elongation of Venus (the perfect angle between the Earth and the Sun) is about 46 degrees that occur once or a maximum of twice a year. During the greatest elongation, Venus can be seen on the horizon for 3 hours before sunrise and 3 hours after sunset.

When is Venus at its brightest in the sky?

Generally, we can see Venus at its greatest brightness twice a year. It starts getting brighter gradually from the beginning of January until it reaches its first peak in March at the magnitude of -3.9. Then the luminosity gradually drops throughout the next three months. From the middle of July, the brightness again starts enhancing gradually and reaches its greatest brightness in December at a magnitude of -4.88.

4 Tips to observe Venus in the best way.

  • Venus is the first shiny dot that appears in the evening sky and the last one to disappear in the morning. It is known as the ‘evening star’ or ‘morning star’.
  • The imaginary path the planets follow around the sun is called the ecliptic which changes slightly throughout the year. The lowest position occurs at the winter solstice and the highest position happens at the summer solstice.
  • Venus is not far from the Sun.
  • To get the best view, you need to reduce the glare. A 25% moon filter helps greatly with this. A dark blue or red filter can reveal a lot of details with the upper cloud. Yellow or green colored filter enhances overall contrast by reducing glare.
