Year 9 Science - Exploring The Universe

The question is asking about the country that the man in question is from. The options provided are America, Italy, Russia/Soviet Union, and Australia. The correct answer is Russia/Soviet Union, as indicated by the answer provided.

NASA stands for the National Aeronautics and Space Administration. This is the correct answer because NASA is a United States government agency responsible for the country's civilian space program and for aeronautics and aerospace research. The other options, such as North American Space Administration, National Astrology and Science Administration, and Never Accept Substances from Aliens, are incorrect and do not accurately represent the purpose or name of the organization.

The first animal sent into space was a Monkey. Monkeys were chosen for space experiments because their physiology is similar to humans, making them suitable for studying the effects of space travel on the human body. The first monkey to be sent into space was a rhesus monkey named Albert I, who was launched aboard a V-2 rocket by the United States in 1948. This paved the way for further animal experiments and eventually human space travel.

Proxima Centuri is the correct answer because it is the closest star to our solar system. It is located approximately 4.24 light-years away from Earth and is part of the Alpha Centauri system. Proxima Centuri is a red dwarf star and is slightly smaller and cooler than our Sun. It is also known to have at least one exoplanet in its orbit, making it an interesting target for future exploration and study.

The correct answer is International Space Station. This is the name of the current space station that is in orbit around the Earth. It is a collaborative project involving multiple countries and is used for scientific research and exploration in space. MIR and Skylab are previous space stations that are no longer in operation. International Scientific research Station is not a known space station.

Sputnik I was the name of the first man-made satellite sent into space. It was launched by the Soviet Union on October 4, 1957. Sputnik I marked the beginning of the Space Age and the start of the space race between the Soviet Union and the United States. This satellite orbited the Earth for three months and transmitted radio signals back to Earth, demonstrating the possibility of sending objects into space. Its launch had a significant impact on scientific, military, and political developments, and it paved the way for further space exploration.

The letter classification of our sun is G. This classification is based on the Morgan-Keenan system, which categorizes stars based on their temperature and spectral characteristics. The G classification represents stars that are yellow-white in color and have a surface temperature of around 5,500 to 6,000 Kelvin. Our sun falls into this category, making it a G-class star.

The correct answer is Corona, Chromosphere, Photosphere, Convective Zone, Radiative Zone, Core. The layers of the sun are organized from the outside to the middle in this order. The corona is the outermost layer, followed by the chromosphere, photosphere, convective zone, radiative zone, and finally the core. Each layer has its own unique characteristics and plays a role in the overall structure and function of the sun.

The correct answer is 4.2 Light years. This means that the star is located at a distance of 4.2 years' worth of light travel away from our solar system. Light travels at a speed of approximately 299,792 kilometers per second, so 4.2 light years would be a very long distance.

Yuri Gagarin is the correct answer because he was the first man to travel into space. On April 12, 1961, Gagarin piloted the Vostok 1 spacecraft, completing one orbit around the Earth. His historic flight marked a major milestone in human space exploration and made him a symbol of Soviet space achievements during the Cold War. Neil Armstrong, Buzz Aldrin, and Michael Collins were astronauts associated with the Apollo moon missions, but they were not the first man in space.

Neil Armstrong walked on the moon in 1969. This is a well-known historical event that occurred during the Apollo 11 mission. Armstrong became the first person to set foot on the lunar surface on July 20, 1969. The mission was a significant achievement for NASA and marked a major milestone in space exploration.

The correct answer is 149 million km. This is the average distance between the Earth and the Sun, known as an astronomical unit (AU). It is approximately 93 million miles or 150 million kilometers.

Our sun is commonly known as Sol, which is derived from the Latin word for sun. It is also referred to as a star because it is a luminous celestial body composed of hot gases. Additionally, G2V is a classification used to describe our sun based on its spectral type and luminosity class.
