Surveying Circumpolar stars Rotate round the celestial pole Remain always above the horizon Rotate round the North Pole Are seldom seen near the pole star Rotate round the celestial pole Remain always above the horizon Rotate round the North Pole Are seldom seen near the pole star ANSWER DOWNLOAD EXAMIANS APP
Surveying When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is θ = 180° - (z + δ) θ = z + δ θ = δ - z θ = (z + δ) - 180° θ = 180° - (z + δ) θ = z + δ θ = δ - z θ = (z + δ) - 180° ANSWER DOWNLOAD EXAMIANS APP
