1. The angular distance between two celestial bodies as seen from Earth.

2. Longitude values are indicate the angular distance between the Prime Meridian and points east or west of it on the surface of the Earth.

3. Angular distance is the distance between two objects measured as an angle from a given point.

4. A speedy match of angular distance method was formulated by curve fitting the table of star pair for realizing rapid match in star pair information catalogue.

5. Matthews calculated the angular distance between the 100 brightest stars in the sky and turned them into 1 million pairs of random numbers, around 61 per cent of which had no common factors.

6. Horizon latitude: the angular distance of a celestial object above the horizon.

7. The angular distance of a celestial body below the horizon.

8. The match excited him(/angular distance.html), because Mayer never missed an angular distance by more than 1. 5 minutes of arc.

9. A fast searching algorithm based on the distribution of angular distance is provided.

10. The calculation results show that the statistical error of interstellar angular distance is reduced from 41" before calibration to 17", the calculation accuracy is improved.

11. The article describes the working principle of the dynamic star simulator based on TFT-LCD and the calculation of the revised star angular distance error.
