9.Pluto- 39.4 AU why do astronomers not measure the distances to stars in kilometers? distance to stars are so great that the number are too large to work with easily.
Some seeds can last for three to four years, such as: 1  asparagus. 2  beans. 3  broccoli. 4  carrots. 5  celery. 6  leeks. 7  peas. 8  spinach.
Seeds stored in the fridge should remain viable for quite a few years, many have reported success after over 8-10 years storage. Though they will go off eventually and as time goes on you can expect the viability and rate of germination to slow until an eventual failure.
