What is the angular size of the sun?
0.5 degrees
Problem 2 – The sun has an angular diameter of 0.5 degrees.
Does Europa see the sun?
Europa [yur-ROH-pah] is a unique moon of Jupiter that has fascinated scientists for hundreds of years. Its surface is among the brightest in the solar system, a consequence of sunlight reflecting off a relatively young icy crust….
| Europa Statistics | |
|---|---|
| Visual geometric albedo | 0.64 |
| Magnitude (Vo) | 5.29 |
How much sunlight does Europa get?
Europa’s surface is made of water ice and so it reflects 5.5 times the sunlight than our Moon does.
Is Europa tidally locked to the Sun?
Distance from the sun: On average, Europa’s distance from the sun is about 485 million miles (or 780 million kilometers). Its orbital distance from Jupiter is 414,000 miles (670,900 km). It takes Europa three and a half Earth-days to orbit Jupiter. Europa is tidally locked, so the same side faces Jupiter at all times.
How do you find the angular diameter of the Sun?
The angular diameter of the Sun is nearly 0.5334 deg. The diameter of the solar disc is nearly (Earth-Sun distance) X (angular diameter in radian) = 149598262 X (0.5334 π /180) = 1392700 km..
How do you find angular size?
The angular size of an object is determined by its actual size and its distance from the observer. For an object of fixed size, the larger the distance, the smaller the angular size. For objects at a fixed distance, the larger the actual size of an object, the larger its angular size.
What is the size of Europa?

Can we breathe on Europa?
Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.
How do you measure the size of the Sun?
865,370 miSun / Diameter
What is the angular size of the Sun?

What is the size and shape of Europa?
Europa is tidally locked, so the same side faces Jupiter at all times. Size: Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth’s moon, but larger than Pluto. It is the smallest of the Galilean moons.
What is the size of the moon Europa?
Size: Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth’s moon, but larger than Pluto. It is the smallest of the Galilean moons.
How far is Europa from the Sun?
Distance from the sun: On average, Europa’s distance from the sun is about 485 million miles (or 780 million kilometers). Distance from Jupiter: Europa is Jupiter’s sixth satellite. Its orbital distance from Jupiter is 414,000 miles (670,900 km). It takes Europa three and a half Earth-days to orbit Jupiter.
