"Umbra" means "shadow". When the Moon enters the Earth's shadow, we call that a "total lunar eclipse".
No, they see night-time. You can see a lunar eclipse (from anywhere) when the MOON is in the earth's umbra.
Masses of planets (in order of mass from most massive to least massive) Jupiter 1.90 x 1027kg Saturn 5.69 x 1026kg Neptune 1.02 x 1026kg Uranus 8.68 x 1025kg Earth 5.97 x 1024kg Venus 4.87 x 1024kg Mars 6.42 x 1023kg Mercury 3.30 x 1023kg Total mass of all eight planets = 2.67 x 1027kg Total mass of the sun is around 1.989 x 1030kg, so the combined mass of all of the planets is only around 0.134% of the the planets and sun together.
During a total lunar eclipse, when the Moon is in Earth's umbral shadow, one will witness the Moon appearing red or orange in color. This phenomenon is often referred to as a "blood moon" due to the reddish hue caused by the scattering of sunlight through Earth's atmosphere.

Changes in Earth's total insolation can be caused by variations in the distance between Earth and the Sun due to the Earth's elliptical orbit (Milankovitch cycles), changes in the Earth's axial tilt, and variations in the transparency of the atmosphere due to factors like greenhouse gas concentrations and volcanic activity.
Humans are a sociable animal. We are not meant to exist in total isolation without suffering mental instability.

The total amount of Earths total water supply that is usable fresh water is less then two percent. The rest is salt water or pond water.
That is a total eclipse of the sun.
The temperature decreases by about 6.5 degrees Celsius per kilometer in the troposphere, so the total temperature change between 3 km and 7 km above the Earth's surface would be approximately 26 degrees Celsius.
