In early 2025, Venus will dazzle within the southwest sky after sundown, incomes its “night star” nickname.
This phenomenon, which happens when Venus will get near Earth, occurs as soon as each 19 months. However, as Venus brightens, it’ll retreat to a slim crescent because it goes via its astonishing moon-phase-like dichotomy.
Here’s every part you might want to learn about Venus in 2025.
Venus because the “night star” and “morning star”
As seen from Earth, Venus would not cross the night time sky because the slower-moving planets seem to do. Instead, it may be seen solely close to dawn and sundown, shifting from “morning star” to “night star” and again once more each 584 days, or about 19 months. Venus orbits the solar each 225 days, in contrast with Earth’s 365-day orbit. Those orbital durations mix to create an eight-year cycle through which Venus seems to orbit the solar 13 occasions, as seen from Earth. During that point, Venus traces a pentagram sample in Earth’s sky each eight years.
Because Venus is nearer to the solar than Earth is and orbits sooner, from Earth’s perspective, Venus is all the time seen near the solar, simply after sundown, when it is referred to as the “night star,” or simply earlier than dawn, when it is dubbed the “morning star.”
About as soon as each 19 months, Venus will get exceptionally brilliant as a result of it will get nearer to Earth than another planet and since its international clouds replicate lots of daylight.
Venus has spent a lot of the second half of 2024 climbing greater into the post-sunset night time sky because the “night star,” however in 2025, its place above the western horizon will peak after which shortly lower.
Venus at dichotomy
On Jan. 10, 2025, Venus will attain its best elongation east within the post-sunset sky, placing it excessive above the western horizon after darkish. From Earth’s perspective, that is the farthest it seems to be from the solar in its present apparition. Just a few days later, it reaches dichotomy, which is when a planet’s disk is half lit by the solar as seen from Earth.
In the next weeks, Venus will get nearer to Earth and seem to shrink to a crescent. Just 23% of it is going to be lit by Feb. 19, when it reaches its highest level within the post-sunset sky. By that point, it is going to be shining at an excellent magnitude -4.9. (Lower magnitudes are brighter.)
If you might have a small telescope, level it at Venus in January and February 2025 to see the planet’s section change. With a telescope, you’ll see Venus seem to develop because it will get nearer to Earth. In reality, through the planet’s dichotomy, the scale of Venus’ disk will enhance by about 60% between Jan. 12 and Feb. 16.

Venus in 2025: Key dates
After its dichotomy and efficiency as an excellent “night star” within the southwest after darkish throughout early 2025, Venus will transfer into the solar’s glare in March and emerge the next month because the “morning star.” Here are some essential dates for Venus in 2025:
- Jan. 3, 2025: Crescent moon and Venus after sundown (separated by 1.4 levels)
- Jan. 10, 2025: Venus at its best elongation east after sundown (47.2 levels angular distance from the solar)
- Jan. 12, 2025: Venus at dichotomy (a half-moon form)
- Jan. 18, 2025: Venus-Saturn conjunction after sundown (separated by 2.2 levels)
- Feb. 1, 2025: Crescent moon and Venus after sundown (separated by 2.3 levels)
- Feb. 16, 2025: Venus at its brightest within the night sky
- March 22, 2025: Venus at inferior conjunction (between Earth and the solar)
- April 22, 2025: Venus at its brightest within the morning sky
- April 24, 2025: Crescent moon and Venus earlier than dawn (separated by 2.4 levels)
- May 31, 2025: Venus at its best elongation west earlier than dawn (45.9 levels angular distance from the solar)
- Aug. 12, 2025: Venus-Jupiter conjunction earlier than dawn (separated by 0.9 levels)
- Sept. 19, 2025: Crescent moon and Venus earlier than dawn (separated by 0.8 levels)
