The most distant human-made object ever sent into space is Voyager 1. Launched by NASA on September 5, 1977, Voyager 1 was originally designed to study the outer planets, including Jupiter and Saturn. After completing its planetary mission, it continued on a trajectory that has taken it beyond the heliosphere, the protective bubble of particles and magnetic fields surrounding our solar system.

Voyager 1 carries the Golden Record, a disk containing sounds and images representing life and culture on Earth, intended for any extraterrestrial intelligence that might find it. As of now, it is traveling through interstellar space, more than 23 billion kilometers away from Earth, making it the farthest human-made object in existence.

Other options in this MCQ are also related to space exploration. Pioneer 10 was an earlier spacecraft sent to Jupiter but is now much closer than Voyager 1. New Horizons explored Pluto and the Kuiper Belt but has not yet reached the distance Voyager 1 has traveled. Eris is not a human-made object but a dwarf planet in the solar system.

This question teaches students about space exploration, interstellar missions, and human technological achievements. Voyager 1 demonstrates how science and engineering can extend human presence beyond Earth. Its continued journey provides valuable data about the solar system’s boundary and interstellar space conditions.

Understanding Voyager 1 and its mission is a key part of everyday science knowledge, particularly in astronomy and space science, highlighting the capabilities of human innovation and the scale of the universe.
