2. How to Use the Moon as a Guide to Find Venus
One answer is to use the Moon as a landmark. On days when the Moon is near Venus, especially when the Moon is a thin crescent, it is easiest to find the Moon first and then look nearby for Venus [2]. Because the Moon is much closer to Earth than Venus, it appears much larger. You can use the large Moon to locate the general area in the sky, and then search for the smaller dot nearby. However, days when the Moon and Venus are close together are limited. This is not a method you can use every single day.
3. How Adjusting Your Eyes’ Focus Helps You See Venus
Sometimes you find the Moon but still cannot see Venus. This might be related to how your eyes focus. According to an astronomy enthusiast’s explanation, when you look at a sky with no prominent objects, your eyes may focus on something close by [3]. If your focus is too close, distant Venus does not appear as a sharp dot but becomes blurry and disappears. To fix this, first focus your eyes on the distant Moon. Then, shift your gaze only 1 to 2 degrees toward the direction where Venus is expected to be [3]. Note that this is a rule of thumb from one enthusiast’s experience, not a result of experimental research. It is not a guarantee that you will see it, but it is advice worth trying.
4. Where to Look for Venus: Near the Sun in the Sky
Venus can only be found near the Sun. Even at its furthest point from the Sun (maximum elongation), it is only about 47 degrees away [7]. Therefore, Venus seen in the daytime is in a direction close to the Sun. The method of using the Moon as a guide works only on days when the Moon and Venus are close and far enough from the Sun. Venus also goes through phases like the Moon. According to NASA, the cycle from one new phase to the next is 584 days, which is different from its orbit period of about 225 days [6]. The distance changes greatly: about 38 million km (23.6 million miles) when closest to Earth, and about 261 million km (162 million miles) when furthest. In 2026, Venus reached maximum brightness around September 19 [4]. Some calendars list this as September 18, likely due to the difference between Universal Time and Japan Time. Venus is hidden by the Sun’s light before and after it passes between Earth and the Sun (inferior conjunction).
5. Safety Rules for Looking for Venus in the Daytime
The most important thing when searching for daytime Venus is safety. Looking directly at the Sun with the naked eye, binoculars, or a telescope can damage the retina and cause blindness. Sunglasses do not protect your eyes from this [1]. Since daytime Venus is in a direction close to the Sun, your gaze might accidentally drift toward the Sun while you search. You should only look in directions that are far enough from the Sun, such as places where buildings block the Sun. Never point binoculars or telescopes at the Sun. For children, it is best to search only on days when the Moon is high and far from the Sun, and always do so with an adult. The greatest danger in daytime Venus hunting is looking directly at the Sun.
6. How to Try Finding Venus Safely Using the Moon Calendar
Check the National Astronomical Observatory’s calendar to find days when the Moon and Venus are close. If the Moon is high and far from the Sun on that day, you can look at the daytime sky with an adult. First, find the Moon, focus your eyes on it to set your distance, and then shift your gaze 1 to 2 degrees at a time. Even if you do not see it, trying different methods is part of the fun of observation. For safety, do not look near the Sun, and never point any equipment at it.
