18 Sept. Prepare to watch. “Venus is the brightest” The last time of this year Observable with the naked eye all over the country. Before the sun rises from the horizon If you miss it, you have to wait for the next time on January 10, 2025.
Facebook NARIT National Astronomical Research Institute Post a message about “On the morning of September 18th, Venus is brightest again.” It stated that September 18, 2023, in the morning before dawn. Venus will appear brightest for the second and final time this year. clearly visible to the naked eye in the east Before the sun rises from the horizon, around 3:25 a.m. onwards, if the sky is clear and there is no rain, it can be observed with the naked eye all over the country.
Venus is at its brightest (The Greatest Brilliancy) when Venus has a relatively large crescent size. and orbits at an appropriate distance from Earth It may have an apparent brightness rating of -4.6 (full moon It has an apparent brightness rating of -12) if observed through a telescope. Venus appears as a moon-like crescent. For other days Even Venus has a thicker crescent. But due to its location far from the world and reduced apparent size The brightness decreased accordingly.
If Venus appears in the sky in the early evening in the west. After the sun sets Thai people will call it “city star” but if Venus appears in the early morning in the east before the sun rises Thai people will call it “Shining Star”
This is for the next brightest Venus phenomenon. It will occur on the evening of January 10, 2025 in the west. After the sun sets.
