Answer 1

Answer:

Satellites provide information about Earth's clouds, oceans, land and air. They also can observe wildfires, volcanoes and smoke. All this information helps scientists predict weather and climate.

Normally, Moon, Venus, Jupiter and Mercury are considered as benefic planets and Sun, Mars, Saturn, Rahu, and Ketu are considered as harmful (malefic) planets. But each planet has its own inherent qualities/traits and behavior.
