Pluto (Dwarf Planet)
(Published on 25. June 2023, 20:03 by Blobz)
Pluto was discovered in 1930, the first object in the Kuiper belt. It was immediately hailed as the ninth planet, but it was always the odd object out and its planetary status was questioned when it was found to be much smaller than expected.
Pluto is made primarily of ice and rock, and has only one sixth the mass of Earth's moon, and one third its volume. Pluto's eccentric orbit periodically brings it closer to the Sun than Neptune, but a stable orbital resonance prevents them from colliding.
In 2006, the International Astronomical Union (IAU) formally redefined the term `planet` to exclude dwarf planets such as Pluto. Many planetary astronomers, however, continue to consider Pluto and other dwarf planets to be planets.
Normal sudoku rules apply: Place the digits 1 to 4, once each, in every row, column and box.
Region Sum Lines: Digits along a blue line have an equal sum N within each box it passes through. Different lines may have different values for N.
Have fun, leave a comment if you enjoy the puzzle!
Solution code: Row 1 followed by Row 4

Hardest part was keying in the solution code!! Because apparently I’m so used to 9x9 sudokus I think row 4 is the first one under the solid/thicker and line not the last row!!! Maybe I shouldn’t be here lol

1:47 after correcting a very silly assumption.
Very easy but still satisfying to solve.
