era,epoch, and period are periods of time that happen in the past
Yes, Rigel is smaller than Deneb.
Yes, the Sun is much smaller than Betelgeuse.
Much, MUCH smaller than the smallest star.
There are 8 planets Mercury (smaller than Earth) Venus (smaller than Earth) Earth Mars (smaller than Earth) Jupiter (bigger than Earth) Saturn (bigger than Earth) Uranus (bigger than Earth) Neptune (bigger than Earth) so 3 smaller & 4 bigger than Earth 37.5% smaller than Earth 50% bigger than Earth
An epoch is smaller than an era or a period.
It is a "period" and then an "epoch".
An era is a time period of indeterminate length, or, geologically speaking, a unit of time, smaller than aeons and greater than periods.
After an era, the next smallest division of time would be an epoch. An epoch is equal to around 10,000,000 years, where as an era is 100,000,000 years.
An era is a geologic division of time that dates from a particularly significant event. A smaller unit of an era would be a period which is further subdivided into an epoch and then an age.
A Period
In geological time a period is smaller than an era but larger than a Epoch.The International Commission of Stratigraphic have divided the time as such from largest to smallest.Super-Eon - (SuperEonothem) (Not recognised by the ICS but unofficially recognised e.g. Precambrian time)Eon - (Eonothem)Era - (Erathem)Period - (System)Subperiod - (SubSystem)Epoch - (Series)Age - (Stage)Chron - (Chronozone) (Not recognised by the ICS but is unofficially recognised usually based on reversal of earths magnetic field)

On the geologic time scale, an era is longer than a period. There are 12 geologic eras in total and they are composed of geologic periods. For instance, the Mesozoic era is composed of the Triassic, Jurassic and Cretaceous periods.
