What does an astronaut experience in space that causes muscle weakness if exposed too long?
Hide Answer
Answer:
Weightlessness
Explanation:
In space, astronauts experience weightlessness due to the lack of gravity. This lack of gravitational force causes the muscles in the body to weaken over time since they are not being used as much as they would be on Earth. Without the constant resistance that gravity provides, muscles can atrophy and lose strength, leading to muscle weakness if exposed to weightlessness for too long.

Who first proposed the heliocentric model of the solar system?
Hide Answer
Answer:
Aristarcus
Explanation:
Aristarcus was a Greek astronomer who first proposed the heliocentric model of the solar system, which placed the Sun at the center with the Earth and other planets orbiting around it. This model challenged the prevailing geocentric view at the time, where the Earth was believed to be the center of the universe. Aristarcus' groundbreaking theory laid the foundation for our modern understanding of the solar system and the relationships between celestial bodies.

What was the first man-made object to land on Mercury?
Hide Answer
Answer:
None Ever Have
Explanation:
Mercury's extreme temperatures and lack of atmosphere make it a challenging destination for spacecraft to land on. As of now, no man-made object has successfully landed on Mercury. The harsh conditions on the planet's surface make it difficult for any spacecraft to survive, which is why no missions have been able to achieve a successful landing on Mercury.

What percentage of the mass of the solar system does the sun contain?
Hide Answer
Answer:
99.86%
Explanation:
The sun contains 99.86% of the mass of the solar system because it is by far the largest object in the solar system, accounting for the majority of its mass due to its immense size and gravitational pull. Other objects like planets, moons, asteroids, and comets make up only a small fraction of the total mass in comparison to the sun.

Which planet has the most eccentric orbit?
Hide Answer
Answer:
Pluto
Explanation:
Pluto has the most eccentric orbit compared to the other planets in our solar system. This means that its orbit is more elongated and less circular, causing it to have a more irregular path around the Sun. This eccentricity is one of the reasons why Pluto was reclassified as a dwarf planet, as its orbit does not fit the traditional definition of a planet.

Between which two planets does the asteroid belt lie?
Hide Answer
Answer:
Mars And Jupiter
Explanation:
The asteroid belt lies between Mars and Jupiter because of the gravitational forces exerted by these two planets. These forces prevent the asteroids from coalescing into a single planet, creating a region of scattered rocky debris. The presence of Jupiter's strong gravitational pull also plays a role in shaping the structure of the asteroid belt.

Scientists have theorized that, when it was 700,000 years old, the universe had expanded and cooled to what temperature?
Hide Answer
Answer:
3000 K
Explanation:
Scientists have theorized that when the universe was 700,000 years old, it had expanded and cooled to a temperature of 3000 K. This temperature marks the point at which the universe transitioned from being a hot, dense state to a cooler, more stable state, allowing atoms to form and light to travel freely. This theory is supported by observations of the cosmic microwave background radiation, which shows the universe cooling down over time.
