Eight planets in order: a static GK revision guide
The planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
The planets in order from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
The sequence to learn
NASA lists eight planets in the Solar System. In outward order they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. NASA identifies Jupiter as the largest and Mercury as the smallest. This is static astronomy GK, not news of an additional planet.
A way to practise without mixing facts
Start by writing eight numbered blanks and filling them from memory. Check the sequence, then separately mark the largest and smallest. Separating position from size prevents a common mistake: “first” means nearest the Sun in this list, not biggest.
Why Pluto is a different question
NASA explains that the International Astronomical Union’s 2006 definition reclassified Pluto as a dwarf planet. Its classification changed; the object did not disappear. When checking an older textbook or poster, look at the publication date before concluding that a newer source has omitted a planet.
Revision questions
Which planet occupies position three? Earth. Which is farthest from the Sun among the eight planets? Neptune. Now close the list and reconstruct it. This self-test is a study exercise, not evidence of a new discovery. Use NASA’s linked planet pages for more detailed measurements.
