why does Venus have the hottest surface temp

Venus has the hottest temp because its closer to the sun and because of the thick atmosphere trapping in heat.

in the model was does Venus need to be for transit

it has to be between the earth and the sun for a transmit

Why are longest seasons on Mars?

it takes longer to change seasons because the farther from the earth and it takes longer to go around the sun causing the seasons much longer

How often do Venus transits occur compared to solar eclipses

IT takes a long time for Venus to come because it has to go exactly between the sun and the earth it happens like twice every hundred year

How is Earth decribed in size compared to other celestial bodies in our solar system

It‘ s alot smaller compared to some of the farther planet like Neptune but its bigger than some planets like Mercury and Venus

What causes the moon to move around the Earth in the specififc pattern of motion it does

The moon is in orbit due to earth’s gravitational pull

what role does gravity play in motion of planets and moons in our solar system

it keeps all the planets and moon in standard orbit

In our solar system, which objects typically orbit the Sun?

Most the planets and asteroids and comets

How do distance changes between two objects in space affect motion in a simulation

changing the distance makes the gravitational pull weaker and could move them out of their orbits.

how does gravity between solar system objects affect space travel

Spacecraft use gravity to help it go faster inside a somethings orbit

what would happen if gravity ceased in solar system

objects would drift out of orbit

why do objects in the solar system not collide regularly

they are held in stable orbit by gravity

asses the effect of the moon being closer to farther from earth

if the moon was closer to earth there would be larger tides if the moon was farther the tides would be smaller.

what causes the predictable orbits of planets and moons in our solar system

gravitational pull

what evidence suggest that our solar system was more crowded

the simulation show debris forming and clearing over time

what is the significance of planetsimals in solar system

there are small debris that eventually made up planets

what happens to debris in the solar system over millions of stimulated years

much debris cleared away but some stay in orbit

what did shapely believe the universe was mostly made of

stars and nothingness

how does the knowledge of light travel time help scientist understand the universe

they use it as a mesure of distance

what data collection method could help prove either shapley or Curtis right

long term observations using telescope

how can the tour of the universe video help us appreciate the universe’s scale

by giving us a visual of the size and time it would take to travel the galaxy

in the universe what force holds galaxies together

gravity

what is the milky way

it is our galaxy that contains our solar system and many planets

the end

good luck
