A skillful con-artist, Paul mysteriously appears at their door one night, injured and bleeding, claiming to be a close college friend of their Ivy League kids, as well as the son of Sidney Poitier. However, the narrow world inhabited by the Kittredges and their public status as people interested in the arts make them easy prey for Paul ( Will Smith). Unfortunately, there is no bright star equivalent to the North Star in the Southern Hemisphere.Fifth Avenue socialite Ouisa Kittredge ( Stockard Channing) and her art dealer husband Flan ( Donald Sutherland) are parents of "two at Harvard and a girl at Groton". To do this, stretch your hands in front of you and measure the angle between the visible horizon and the North Star. If you are in the Northern Hemisphere, you can use your hands to find your current location’s latitude.

The angular diameter of a full Moon is about 30', while the angular diameter of the Sun is around 32'. Remember to never look at the Sun directly without any eye protection! The Sun and the Moon are the only objects in the sky whose angular size is visible to the naked eye.

Angular SizeĪngular size or angular diameter of a celestial object is the angular separation between opposite edges of the object. With these simple measuring rules in your hand, you can not only understand basic stargazing jargon but also tell other budding stargazers where to look for a specific celestial object in the sky. It is important to note that such measurements are approximate – not everyone has the same sized hand. Your little finger at an arms length is about 1° wide.Your three middle fingers will span about 5°.The tip-to-tip span between your index finger and your little finger is 15°.The tip of your little finger and your thumb will span about 25°. Open up your fist, stretch your little finger and thumb as far as you can and curl down the rest of your fingers.This means that angular distance or angular separation between the two stars is 30°. The North Star (Polaris) and Dubhe, one of the northern pointers of the Big Dipper are 3 fists apart. This means that any two objects that are on the opposite ends of your fist will be 10 degrees apart. The width of your fist will approximately be 10 degrees. Make a fist, with the back of your hand facing you.Hold your hand at arm’s length and close one eye. The zenith is always 90° from the horizon.

The point right above you in the sky is the zenith. The other half of the celestial sphere is below the horizon and cannot be seen. If you look above at the sky, you will see only half of the sky i.e. Imagine the sky as a big hollow sphere with the Earth at its center – let’s call this the celestial sphere. There are 360° in a circle or sphere, each degree is divided into 60' and each arc minute is further divided into 60". Like our modern-day timekeeping, the angular method is based on a sexagesimal system – a numeral system with 60 as its base. While angular separation primarily describes the apparent distance between celestial objects, as seen from Earth, it can also be used to suggest their actual distance from one another. Known as angular distances or angular separation, distances are expressed in terms of degrees (°), arc minutes ('), and arc seconds ("). Measuring Anglesīecause of this, astronomers measure the distance between celestial objects based on the angle they make with an observational point on Earth. Our conventional methods of measuring distances between two objects on Earth make very little sense when measuring the vast distances between celestial objects.
