These all pass within 5 degrees of the zenith: Hamal (Alpha Arieties), Aldebaran (Alpha Tauri), Algieba (Gamma Leonis), Arcturus (Alpha Bootis), There are other fainter ones as well
Daylight starts and ends with the centre of the Sun theoretically at a zenith distance of 90 degrees 50 minutes. It is more than 90 degrees to allow for atmospheric refraction and also because the top edge of the visible Sun must be level with the horizon. The length of daylight depends on the Sun's declination and the observer's latitude. When these two factors are equal the Sun passes overhead at midday.
If the Sun passes through your zenith on December 21, you would be located near the Tropic of Capricorn in the Southern Hemisphere. This date marks the December solstice, when the Sun reaches its southernmost point in the sky, making it directly overhead at midday for locations within the tropics.
No, not all stars pass through the zenith. The zenith is the point directly overhead an observer, so stars that are close to the celestial pole (North or South) may not pass through the zenith at all from certain locations on Earth. Stars near the celestial equator are more likely to pass through the zenith as they appear to move across the sky.
To accurately determine the solar zenith angle for a specific location and time using calculations, you can use the formula: Solar Zenith Angle = 90° - (latitude + declination angle + time correction factor) where: Latitude is the geographic coordinate of the location Declination angle is the angle between the rays of the sun and the plane of the Earth's equator Time correction factor adjusts for the time of day and year By plugging in the values for latitude, declination angle, and time correction factor, you can calculate the solar zenith angle for the desired location and time.
solar altitude angle= (90 degree - zenith angle )
The sun passes through the zenith twice a year at each tropic line. This will occur once at the Tropic of Cancer (23.5°N) and once at the Tropic of Capricorn (23.5°S). So, in a full year, the sun will pass through the zenith two times.
Perth is at 32 degrees south and on the summer solstice the Sun's declination is 23½ degrees south. Therefore the Sun is 32-23½ degrees or 8½ degrees from the zenith, that is 81½ degrees above the horizon.

That depends on your latitude. Also, it does NOT depend on the season. If a star passes near the zenith in Summer, it will also pass near the Zenith in Winter, although it may not be visible in one season or the other (when it passes near the Zenith during the daytime).
The "tropics" are the part of the earth between 23.5 degrees North or South and between these lines the weather is generally hot all year round.On the tropic lines themselves, the sun only passes through the zenith once per year (on the June or December solstice) but any location between these lines, the sun will transit through the zenith on two days of the solar year.
If the Sun passes through your zenith on December 21, you would be located near the Tropic of Capricorn in the Southern Hemisphere. This date marks the December solstice, when the Sun reaches its southernmost point in the sky, making it directly overhead at midday for locations within the tropics.
